Zebra Stripes white on black or black on white?
« on: 03/11/2003 20:44:01 »
Are the stripes on a Zebra black stripes on a white background or white stripes on a black background; or, simply alternating black and white stripes?

Actually that's how you can tell the difference between a male and female zebra - the males are black with white stripes, and the females white with black stripes...

Huh, I didn't think there was a color difference based on gender, interesting.

Hahaha. Actually, the true test to differentiate a male zebra from a female is this. The male zebra has stripes on his penis, as the female does not. It works every time.

Actually there is color difference based on gender in cats.  If a cat has black, white and orange fur it is always female.  We learned the genetics in high school science, but I've long since forgotten.  Any geneticists want to have a go at it?

I've always wondered about the genetics of a calico cat and why they are always female.  I hope someone has an answer.

You're right Donnah. I've been doing this kind of genetics in school.

In cats, one gene for coat colour is present on the X chromosome but not on the Y chromosome. This gene has two alleles, orange(B) and black(b). Female cars that are heterozygous have tortoiseshell coats (orange coats with dark patches). So you can have:

X(B)X(B) - female orange coat
X(B)X(b) - female tortoiseshell coat
X(b)X(b) - female black coat

X(B)Y - male orange coat
X(b)Y - male black coat

So a male cat can never have a tortoiseshell coat.

i've heard they are offering gender re-assignment on the NHS now... so there is a possibility! ;)

Oh yes, as do giraffes. Only giraffes have spots on theirs (male) and the females do not. The female's penis has no spots, as the female zebra has no stripes on her penis. However, the male zebra has spots on his vagina and the male giraffe has stripes on his vagina. It's very confusing.

It's really sad what insomnia can do to your brain.

Female hyenas produce so much testosterone that they develope false penis. This is true! And I don't have insomnia.

Presumably the female hyenas "penis" is actually clitoromegaly (an over-enlarged clitoris) which develops in response to the high testosterone levels ? Why do they have such rampant testosterone though ?

Female hyenas are the dominant members of their pack. I guess their increased testosterone is so they can keep control of those unruly males.

Donnah,
You and I don't need a shot of testosterone.  We already have more balls that a lot of the men I know.

If they had more testosterone than males, wouldn't they be male?

Nancy, you crack me up.  When I was growing up I could never figure out why a penis was a prerequisite for going hunting or taking Shop & Automotives class, or how a vagina automatically prepared one for cleaning, cooking and childcare any more than I could understand why boys couldn't take Home Ec.  Happy to see the young ones have more choices now.

I pretty much always liked the girls in shop class better than the ones in home ec.  The were more interesting and usually smarter.

I don't think so. Remenber they still got the XX chromosomes which determine their primary sexual characteristics.
