Biology Extra Credit Question... **ANSWER POSTED**

[BethinIrving]

LOL!

Please retake your Biology 101 and go back and read your high school Biology book section on Genetics and Influences on Genetics.

I think ya mighta snoozed through a class.

psst -- I gotta wonder how serious your question really is!!

LOL!!

The answer to the question, if you've quoted it exactly, is "Humans!" Our SEX, which is a matter of anatomical fact, is determined by our chromosomes. But our GENDER, a socially constructed concept, which differs in diff places and diff times, is determined after birth!

BethinIrving-
This is a serious question. I am in Honors Biology and even though the answer to the question may not be serious to you, IT IS TO ME. I obviously do not know what the answer is so I am using different ways to find it. We just started the chapter. I would appreciate it if you would leave out these condescending comments. FYI- I am taking the class as of NOW. I am in HIGHSCHOOL. Give me a break!

Chickiebaby-
That does make sense and I may have to take that into consideration, but I think my teacher intended for "sex" and "gender" to be interchangeable. Since sex/gender is determined by our sex chromosomes, she wants to know which animal's sex/gender is not determined by the chromosomes, but determined after birth.

Portia-
As stated in the first post, my teacher said it was not a reptile. Turtles are reptiles.

I think a bunch of different amphibians have environmentally determined sexual differentiation. They seem to be born/hatched with a neuter sex and environmental factors determine the final gender; remember Jurassic Park and the frog DNA allowing the gender switch in the dinos??? Google amphibian sexual determination and you'll get alot of sites.

Even in humans, sexual determination can be changed by environmental factors to a small extent. Testicular feminization being one situation that has had a lot of play time in fiction lately; but exists in the real world. This results in a phenotype female with a 46XY genotype, genetically male.

Rooster, at some point in time you will know when comments are deliberately condescending and when they aren't. Mine certainly wasn't deliberate.

I apologise that my posting provoked such a negative response in you. But, your question was delightful and funny. That's why I took such a lighthearted approach to it.

Cheer up! You will have many serious challenges as you go through life. This isn't one of them.

Take care, and congrats on being an Honors Student.

My husband has a degree in bio-engineering. He says the answer is fish.

Gender pressures in the population determine what sex the hatchling will be.

He did a lecture on it in college.

What you are thinking of is Parthenogenesis. I alos thought this could be it...

Oh, wow! Thanks Miss Prissy! Thank you for your help. On Monday I'll ask my teacher to see if it is right, if not, I'll let you know and tell you guys the right answer.

Just a suggestion to possible look into further.. I don't have time right now...

However, we're still leaning toward fish right now. (Clownfish?)
