Hi iam doing some biology homework and I don’t understand what this question is asking “discuss why knowing an individual is XX or XY interms of chromosomes is not sufficient to know their biological sex?” What iam suppose to do?
In: Biology
Sex development is determined by genes on the X and Y chromosomes. One of the most important ones is *SRY* on the Y chromosome. Having this gene makes the embrio develop testicles, which then produce hormones that lead to development of other masculine traits. If the *SRY* gene is nonfunctional, you can get an XY woman. If the *SRY* gene gets translocated to the X chromosome, you can get an XX man.
There are many other genes and organs involved that will determine the final phenotype.
