What is lyon's hypothesis?
Females carry two X chromosomes. One is inherited from each parent. Both of the X chromosomes do not have to be activated. One of the X chromosomes is neutralized. However, the extra X chromosome can be reactivated in some cases. This does not means that females need only one chromosome. Females with only one X chromosome have genetic conditions that can cause disabilities such as Turner Syndrome.

Is there a difference between the chromosomes of men and women?
Human females are XX; males are XY.In humans, females have 22 pairs of chromosomes called autosomes, plus one pair of sex chromosomes, consisting of two copies of chromosome X. The X chromosome is between chromosomes 7 and 8 in size. Males have the same autosomes, but their sex chromosomes consist of one X and one relatively tiny Y, which is the shortest chromosome humans have except for chromosomes 21 and 22.Many other animals determine their sex the same way. But birds, moths, and butterflies are the other way round (males are WW; females WZ), and some animals use a different system altogether, such as whether the egg is fertilized or not: honey bees, for example.
What theories explain the evolution of gender and development?
First, it should be noted that the development of gender (sexual dimorphism) is a subject separate from that of the evolution of sexual reproduction. Sexual reproduction had already existed for a long time when the first sexually dimorphic species evolved. Sexual dimorphism, gender, is the situation wherein there exist distinct roles in the reproductive cycle, and morphologies associated with each role have diverged. One way that sexual dimorphism could have evolved is through the difference in size an number between male and female gametes. Males are typically able to produce gametes in prodigious numbers, while females usually produce far fewer and larger gametes. This makes males more redundant, in some cases leading to male competition over females, while females may have the "luxury" of "picking and choosing" from the redundantly available males. A difference in gender roles and associated morphology may follow from this. This is one way for gender and sexual dimorphism to evolve, but not the only way.
