Half-Male, Half-Female Fowl Explain Birds' Sex Determination
Kanan excerpts from a BBC report out of Scotland: "A study of sexually scrambled chickens suggests that sex in birds is determined in a radically different way from that in mammals. Researchers studied three chickens that appeared to be literally half-male and half-female, and found that nearly every cell in their bodies — from wattle to toe — has an inherent sex identity. This cell-by-cell sex orientation contrasts sharply with the situation in mammals, in which organism-wide sex identity is established through hormones."
Kanan also supplies this link to some pictures of the mixed-cell birds.
So would one of these hermaphrodite chickens be called a half-cock?
I agree with the section "Clucking confusing."
Prize for the least funny pun.
That's somewhat close to the rate of intersex conditions in mammals, including humans.
The Christian Right is Neither (Christian nor right). See: Matthew 23, Matthew 25, Ezekiel 16:48-50
Shouldn't that be hermaphorochicken?
So each cell has it's own this.getSexualOrientation() function.
Whereas mammals have a global static variable where SEXUAL_ORIENTATION = MALE or FEMALE.
This is interesting because I thought we all inherited from a common ancestor. Was sexual orientation not defined in the root class?
I suppose I deserved to be subjected to bad puns just for opening this thread.
"Intersex Chickens" is just one of those topics one should avoid on Slashdot. What was I thinking? /me escapes before "chicks with..." jokes start.
Someone had to do it.
They're not the first ones to be checking out a nice-lookin' bird and then see from another angle that "she" is really a man.
Information theory is life. The rest is just the KL divergence.
Now you'll have a fresh material to argue which came first...
First rule of holes; When in one, stop digging.
When I was about five years old, I happened to find my grandfather's copy of How to Sex Chicks. I didn't know much about the reproductive act, but I knew that there was something provocative about the phrase "sex chicks", although the book itself, on close examination, seemed innocent enough (how to tell if a baby chicken is a boy chicken or a girl chicken).

To get to the other gestalt.
Seriously. What I'm inferring from the article is that you can see the difference in the cells, e.g. male vs. female....
So how the hell have they never noticed that female and male birds have these slightly different cells before, and reached the non-hormone driven conclusion before this?
It's well known that birds have a completely different sex determination mechanism than mammals. For example, mammals (other than the platypus) use X/Y or X/0 chromosomes to determine sex. Birds on the other hand use Z/W chromosomes for sex determination, as do most fish, some insects and some reptiles. So the big eyed "Ooooh, who would've thunk that birds aren't handling it the way we mammals do?" attitude of the article seems kind of silly considering we've known about this striking difference for a long time. Imagine that it actually mattered... Suspect they just wanted a reason to publish those cool pictures.
So I wonder if the applies to spices that can change sex at "will". I seem to recall that there are some fish, frogs and lizards that can do this.
Now we can produce twice as many chicken breasts.
I suppose we’d better not be going off half-cocked, though. More grant money!

What does this mean for "the birds and the bees" now?
really puts me in a fowl mood...
Is Sam a straight cock with a confusing lesbian side?
...Nevermind. We're on Slashdot after all... *sight*
that as we all know is 100% male oriented.
Did anyone else wonder how " Half-Male, Half-Female Fowl" can explain anything to anyone, seeing as they are...fowl?
When I was younger my grandfather told me that one of the ducks he had switched sex's when the female of the trio died,
I never believed him...
But maybe it was more plausible then I thought
Holy Shit, Talking Birds!!!!
No need for the ridiculous frogs in the plot anymore !
I wonder if this is true for dinosaurs as well and if certain events affecting reproduction contributed to their extinction.

Why did the intersex chicken cross the interstate?
Another story about Al Gore.

Are you suggesting that the Gay Agenda was what wiped out the dinosaurs?
I suspect the real events that affected their reproduction involved Mass Quantities of Death, and the difficulty in getting Zombie Dinosaurs to reproduce.

Any bird can teach you something about the birds and the bees, assuming of course, that you're not a bee.
Like the chickens, his joke went off half-cocked.
Scientists point out problems, engineers fix them
altslashdot.org: The future of slashdot.
the fact that it can talk, and apparently give a scientific lecture, would have been seen as much more newsworthy.
You know what they say about opinions. They're all fabulous!
Wow. How often will you ever read that outside of a police report about a domestic dispute?
I scream. You scream. I assume that means we're both acquainted with the problem. We proceed.
.. wasn't that interesting. The only reason to click on this story is to read some /.ers comments.
They call it Chimerism. Sorry to cook your goose... video part 1 video part 2 Link 1 Link 2
New slashdot layout sucks.
yes, you're suggesting that maybe the cock came first?
not exactly unheard of
> That's somewhat close to the rate of intersex conditions in mammals, including humans.
Yeah, there are chimeras:
http://en.wikipedia.org/wiki/Chimera_(genetics)
Back in my Bible School I distinctly remember in the Book of Job around Chapter 27 that "His breasts are moistened with milk" to be a distinguished cause of how men are expected to raise female children from their breasts and the wives are to raise the male children from their breasts akin to correct the societal acceptance of gender. It is obvious that subconscious reasoning is established early in the attractions of developing minds to what they perceive as their drive.
On a related note, I am a hermaphrodite; I have both fully functioning male and female organs; My clitoris is at the tip of a shaft that many call a penis, but it's just something many people would imply usage to such fluid exchange. Even my girlfriends say that there is an ongoing study about how during certain conditions of diet and environmental factors their all-female body can produce viable fluids that would cause female ovaries to be fertilized when presented from one woman to another. There are even studies showing that the fertilization factors of fluid of men or women interacting with one-another is much to consider as more stimulation for non-receptive egg to begin dividing and incubating what was already inherent as to it's anchor upon the womb wall. This competes against male seminal fluids in the manner that what is thought to be non-competitive biological functions of the same species is actually an environmental trait not of this world that was introduced some time ago into all species to make their lives more redundant in retaining genetic health in any given species.
Evidence of it happening recently is in reduced populations of only reptilian organisms. Outside of reptilians, the obvious commemoration of fish behaviour is overrated. In reptilians, it is more a 3rd gender. What is seen in mammals today could be attributed to enumeration more-so as a complete 5th gender respective of Royal family lineage dating back to Germany and even some factors of Scotland. Consider how the base brainstem of man-kind, otherwise known as the Archon center, is identical to a primitive reptile; this follows the course of Bible Studies that suggest many of the de jure men documented in the Holy Bible would be sired in means of not self-preservation but interaction with a more functional gender not on this planet. This dates back to areas of Scotland and proto-Ireland concerning druidism and competition to the serpent race that makes various appearances in the Holy Bible. Islam if for the most part very silent on the subject in these anatomical forms, but considers surgical correction to be the common route, as opposed to Budhism that would rather accept this as evidence rather than anomaly and the gifted creature to appraise and harness oneself in look for another receptive creature like itself. Budhism follows into the Specie(al) isolation as a Garden of Eden approach for likeness of the matter to reveal a cause to rise from dormacy.
So the interchange of organs go, just as you would say; ovipositors only a dominant trait among non-mammalians and non-reptiles, whereas unusual lifeforms as reptilian or insectoid it's all kissing lips for fluid exchanges or beverage mixing just as what's happening between spontaneous perpetuation between tribal lesbians.
That's different. Chimeras are the result of the cells of two individuals combining into one organism. Chimeras are unlikely to be intersex as one cell line will form the sexual organs. Intersex refers to individuals with ambiguous sexual characteristics, and can be caused by several factors. Neither of these can result in gyandromorphism in humans.
Because of intermittent interest in interacting with the interstate's surface.
Ezekiel 23:20
Trolls like you, just look every witch-way to criticize KJV AV 1611. It says right in that book about a man's breasts producing milk, and even catalogues the fact early in the book of Genesis that God made man "male and female."
If you use anything from Zondervan, then you don't have a right to quote their copyright and trademark interpretation of scriptures. Notice how Zondervan has produced over 15 different interpretations of Biblical script and forbids anyone to use it, while King James Version is traced to the actual Royal families that endured every hurdle of a corrupt Catholic Church from doing better in Scotland.
KJVAV1611 is public domain, in your hands because of the blood of many innocent and penitent had endured persecution at the hands that kept your own eyes from holding the same scripture.
