Question

Answer true or false

(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.

Expert Solution

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.
