Why are men with older brothers, but not men with older sisters or those who are only children, more likely to be gay? a. A mother’s heightened immune response with subsequent male-fetus pregnancies affects brain development. b. Older brothers are likely to deride and belittle the youngest brother, creating a more sensitive, fearful, and confused individual. c. Older brothers are more likely to protect and guard the youngest brother, shielding him from rough-and-tumble play and traditional masculine rituals. d. Mothers are more likely to unknowingly treat their youngest sons like daughters.

d. Mothers are more likely to unknowingly treat their youngest sons like daughters.

Explanation:

This is because you find that the mother of the younger son is always hiding the young man from most things, thinking that they are protecting them from harm but its a different story.Mothers often spend more time with the boy because at times she will feel that hes being bullied by the older brothers and see the need of making sure that he is secured at all times.This in turn creates confusion in the young man because hes always surrounded by the female figure and ends up learning or picking up some of the female behavior.

Mothers choose to treat their youngest sons  like daughters when they mostly have sons and not daughters.They do this by trying to close that void of not having a daughter by teaching their sons to do activities that females normally do.
