Male Baldness Info

if u can help me plz leave ur email so i culd email u plz,there r wayyyyyyy to much 4 me 2 post.
heres 1:
There is an autosomal gene that controls baldness,and its expression is sex influenced,so that the gene for baldness(B) is dominant in males but recessive in females.In females,the allele B1 for nonbaldness is dominant over the gene for baldness.If a heterozygous nonbald woman married a nonbald man,wat will be the appearance of their children?what are the possibilities for each sex.

Could baldness be seen as a more evolved state, or do you think it will be wiped out by sexual selection for the unattractiveness of it? If it gets eliminated wouldn’t though, wouldn’t the same mutations that caused it in the first place eventually cause those with hair to eventually lose it as well since it’s not a necessity for survival?
Thanks in advance
