Question

The biggest “genetic marker” for alcoholism is the Y chromosome. Give a plausible scenario of how the Y might have achieved this status. The biggest “genetic marker” for anxiety disorders is the absence of the Y chromosome. Give a plausible scenario of how the XX genotype achieved this status.

Answer 1

The biggest “genetic marker” for alcoholism is the Y chromosome. A plausible scenario of how the Y might have achieved this status is the fact that; since the genetic marker is carried on the Y chromosome. There is a greater chance that the male will receive this trait. However, this does not cancel out females.

The biggest "genetic marker" for anxiety disorders is the absence of the Y chromosome. A plausible scenario of how the XX genotype achieved this status is the fact that; the genetic marker for anxiety disorders in carried on the X chromosome. When an XX is crossed with an anxiety-prone trait and non-anxiety prone trait, the individual is at a greater risk to have anxiety.
