i believe it should be "gender" not "fender". males have and x and y chromosome and females have 2 x's. so the mom always donates an x chromosome to the baby, the dad can donate an x and that makes it a girl or he can donate a y and then the baby is a boy.

Sex chromosomes control the gender in humans. Specifically, the Y-chromosome makes an individual a male. Lack of a Y-chromosome makes an individual a female. Even if there are an unusual number of sex-chromosomes, these rules apply.
Females: XX, X, XXX, XXXX
Males: XY, XXY, XYY

they could't. Creationists truly can not supply a reliable, purpose clarification to the fusion of those 2 chromosomes and different products of evidence for evolution. @ Dems hate previous human beings: human beings are not apes? truly? What are we then? Taxonomically, we are definitely apes. We no longer only share that chromosomes, we even have comparable viral insertion factors in our DNA.
