comment upon "all males are genetically female"?

Answer 1

In all males and females there are 44 autosomes and one X chromosome. So out of a total of 46 chromosomes 45 are common to both.With respect to Y chromosome one can say that it has only a few genes to give maleness.
In the female, out of the two x chromosome only one remains active at any point of time.In the male too only x chromosome is present.
You could by corollary coin an expression: ALL FEMALES ARE GENETICALLY MALES.

Answer 2

Okay, that all sounds overly complicated. (by the way, in regards to the above, all females couldn't be male because they would need to have a working Y chromosome, which they don't. If a male had only the X active he would be female.)

Anyway, I suspect what the comment means is in relationship to the genetics at fertilization. All embryos contain the X chromosome from the mother. The sex is determined by the father who will contribute either another X, or a Y for a boy.

By default, the growing fetus is always female. It is the presence of the Y chromosome which 'turns on' the changes which make it develop into a male. No Y, no boy.

Meaning, in short, that the baby is automatically female unless the male contributes his Y which redirects the development of the sex organs into the male anatomy.

.....................

What they are saying is that at fertilization all are originally female. However, genetically, once the Y chromosome turns on, it is male. Males simply CANNOT be genetically female from that point on. If they were, they would be women.

Now, I'm hoping I didn't just make that sound as complicated as all the others.

Answer 3

The embryology of human being is actually female because it grows inside a female body.But the so- called SRY gene in the Y chromosome only determines the morphology of the foetus to be male. The Y chromosome contains no polycopies for the genes that give enzymes for conversion of Androgens to Oestrogens to supplement the genome of the accompanying X chromosome.SRY - Sex- determining Region in Y chromosome.

Answer 4

It is on the genetic pattern.
Males have XY Chromosomes.
Females have XX Chromosomes.

Answer 5

Well a clown fish (I think it was a clown fish) is a female at first, and then later on in its life, it becomes a male, but I'm not sure if that counts.

There are also some creatures that are...either both male and female, or neither male or female (not sure which).

Answer 6

Bunk.
In placental mammals, males get the Y chromosome at conception, so in placental mammals, no males are genetically female.

Answer 7

may be there are xy in males & xxin females .But while thse males r born there may be differ in cr.no. .So sometimes they r genetically female.
