You mean to say can intense exercise change a female to a male.
Now I haven't read every medical journal, but I seriously doubt a 30 minute run has caused a change in gender in the past, nor will it ever.
The genotype that typically results in a human female is XX. This means that females have two X chromosomes.
XX
XX for female and XY for male. -anonymous18_K
To determine if the XX genotype is dominant, we need to know the specific allele interactions involved. In general, dominance refers to the relationship between alleles where one masks the effect of another. For example, in many cases, a dominant allele will overshadow a recessive one in phenotypic expression. Therefore, without additional context about the alleles in question, it's not possible to definitively state whether the XX genotype is dominant.
A male grasshopper has two different sex chromosomes, XY, while a female grasshopper has two of the same sex chromosomes, XX. This difference in sex chromosome composition determines the sex of the grasshopper.

That is not public information but her genotype is probably XX like most females.
XX
The genotype for a male is XY. A female is XX. The 23rd homologous pair is the sex gene that determines this.
It results in a female:) im pretty sure you go to primavera like me, biology is tough isn't it?
a biologically male individual. The XY genotype typically refers to the genetic makeup of males in humans, where X represents one of the sex chromosomes inherited from the mother and Y represents the sex chromosome inherited from the father.
