um asexual speicies like some corals dont HAVE a gender at all. they are nither female nor male

intrresting (byt off topic) fact i just rembered, salamanders are the only spices which can reproduce in there juvinile stage. the mexican walking fish which is juvinile stage of the salamander can sexually reproduce before it becomes an adult and a lot have compleatly lost the ability to mature now

Considering how many 12-14-year old girls there are running around pushing prams or toting babies on their hips, I'm a bit dubious about salamanders being the only creatures to breed in their juvenile stage.

Not all male. There are female seahorses.

How would an all male species work? They'd have to ejaculate out diploid sperm that would then grow into new organisms...

 

In birds the sex-chromosomes are reversed. Males have XX and females have XY..
So what's a male and what's a female ?

Good question...

I guess the one with the penis is male.

 

Birds don't have penises

Male produces sperm as its sex cells, and females produces eggs as the sex cells

 

Yep

lol

 

More:

The cells that eventually turn into either eggs or sperm – known as germ cells – are identical in male and female embryos.
--
“In females, meiosis begins before birth and eggs are produced, whereas in males, meiosis begins after birth and the result is sperm.”
--
They also discovered an enzyme present in male embryos that wipes out retinoic acid and so suppresses meiosis until after birth, resulting in sperm production.

But their manner of exchange is different. They change their own survivability, not just that of their offspring.

 

Whichever one produces the gamete with the mitochondria in it.

 

Should I start running all my OP's past you before I post?

 

That's true. They do however perform fission straight after.
But yea, it's not quite the same.

Is the female. Thanks

Either that, or stop being vague and/or stop changing the subject of your own threads after a few pages

According to the biologists I have to put up with everyday. Females are whoever produces large gametes and males are whoever produces small gametes.

 

Yea, but is this true for all animals ? Perhaps it is, but doesn't that rather indicate that the one that nurtures the fertilized egg internally is the female ?

 

no whining when I send you the OPs to review then

 

I promise I won't whine

Weren't mitochondria once a separate species which lived symbiotically with our genetic ancestors ?
