(5)Baldness is an X-recessive linked trait. Baldness is epistatic to curly hair" which is dominant over straight hair. The gene which determines whether the hair is curly or straight is on an autosome. A bald male has a wife with straight hair and curly headed daughter. His daughter has children with a male with straight hair. The chance that one of their male offspring has a full head of curly hair is 1/2 *for the purposes of this question, assume that if someone is bald, they will not have a full head of curly head even though in real life they might when they are younger. 6. When researchers studied hypertension (high blood pressure) in twins, they found a concordance rate of 36% for identical twins and 8% for fraternal twins. True or False: Since the concordance rate for identical twins is much less than 50%, genetics does not play a role in hypertension.

Introduction
- Baldness is X-linked and recessive, which means that any male with an X chromosome with a baldness allele will be bald.
- Epistasis is a gene interaction in which the expression of one gene masks the expression of another.
- The concordance rate in twin studies refers to the percentage of twin pairs who share a specific genetic trait or condition. A high concordance rate indicates that the trait or condition has a strong genetic influence, whereas a low concordance rate indicates that environmental factors may also play a role.
