The allele for pattern baldness (B) is dominant, and the non-bald allele (b) is recessive. Susan's

mother has the genotype bb, while her father has the genotype BB. Susan and her three

brothers all have the same genotype (Bb). All of Susan's brothers have pattern baldness, but

she does not. Which statement best explains why it is possible for Susan to have the same

genotype as her brothers without having pattern baldness?

A-Pattern Baldness is a sex-linked trait

B-Pattern baldness causes random mutations

C-pattern blandness isn't heterozygous trait

D-pattern baldness skips every other generation
