>>94740311>the gender changes with temperature because THE GENES GENERATE BIOCHEMISTRY THAT ENABLES GENDER TO CHANGE GENDER WITH TEMPERATURE>literally no form of biological expression in multicellular creatures past a certain size exist outside the boundaries of genes.I expressed myself badly, so it's on me. I meant to say that there wasn't a gene explicitly set to determine gender as the XX and XY do. Rather, both gender were coded in our gene and it was the exterior environment who who determined which of the plan would be followed. But the gender wouldn't be set at conception by the meiosis of a specific pair of gene.
So to make myself clear, for many non-mamal, the DETERMINATION f gender is not set by gene, bu by exterior environment. The plan to build a gender AND the other STILL exist nonetheless in the genes itself, but how one get picked over the other, is not determined by genes.
for mammals, on the other hand, the determination of the gender IS set by the specific genes, XX and XY.
XX and XY were a later addition for mammal, but the plan for both gender exist in us. XX and XY doesn't contain the manual for the gender, but rather, activate one plan or the other who exist accross many of our genes.
>And true hermaphrodites don't existIt does. But it's very rare. It require:
-double ovulation
-that one of the eggs get fecundated by an Y while the other is by an X
-the subsequent merging of the two genes
Don't know if you have heard of person who actually have two different sets of genetic material, it's due to them absorbing their sibling in the womb and when they are of opposite gender, you have a True hermaphrodite, with both XX and XY being part of their genetic matchup.
