Can the lyon hypothesis be tested in a human female who is homozygous for one allele of the x-linked g6pd gene? why, or why not?

No, Presence of different alleles for an X-linked gene is required to test the Lyon hypothesis.

Explanation:

According to the Lyon hypothesis, to compensate the dosage of X linked genes in males and females of mammals, one X chromosome in all the cells of a female mammal is inactivated and the presence of the gene on the other X chromosome is expressed.

Inactivation of the X chromosome is a random process, that is, either maternal or paternal X chromosome may be inactivated during early embryological development in females.

To test the Lyon hypothesis, the expression of alternative alleles of an X-linked gene in the cells of a female mammal is studied. Given that the human female is homozygous for an X-linked gene, all of her cells would express the same allele for the gene, and the Lyon hypothesis can not be tested.

cats appear to have glowing cat eyes because the back of their eyeballs includes a special reflective surface called the tapetum lucidum. this lets them see better during the night, giving them a much better vision.
