The probability of 113 and 114 being a carrier is respective

The probability of 11-3 and 11-4 being a carrier is, respectively: 1/3, 1 1/2, 1 1/4, 1/2 1/2, 1/2 1/4, 1

Solution

Answer: ½, ½

Explanation:

II-3 has ½ chance of being a carrier

II-4 has ½ chance of being a carrier

X-linked recessive inheritance:, two copies of a disease allele on the X chromosome are required for an individual with two X chromosomes (a female) to be affected with an X-linked recessive disease.

For a carrier female, with each pregnancy there is a one in two (50%) chance her sons will inherit the disease allele and a one in two (50%) chance her daughters will be carriers.
