What is the probability of the birth of healthy children from a marriage with a man suffering from hemophilia and a healthy (homozygous for the hemophilia gene) woman (the recessive gene that causes hemophilia is lacolized in the X chromosome)
Let’s determine the genotypes of the parents, based on the condition.
Father: X (a) Y – sick.
Mother: X (A) X (A) – healthy.
Next, we will determine the genotypes of their children.
Boys: X (a) Y – healthy.
Girls: X (A) X (a) – healthy, but are carriers.
Thus, the probability of having healthy children in this family is 100%, but all girls will be carriers of the hemophilia gene.
