Question

One result of x-linkage is a crisscross pattern of inheritance in which sons express recessive genes of their fathers and daughters express recessive genes of their mothers. one result of x-linkage is a crisscross pattern of inheritance in which sons express recessive genes of their fathers and daughters express recessive genes of their mothers.

a. True
b. False

Answer 1

false

Step-by-step explanation:

Answer 2

False. Most x-linked conditions occur on the X chromosome, because the Y chromosome contains roughly 40 genes, and the conditions of X-linked diseases are primarily recessive.
A male with an X-linked disease will express the phenotype, only passing his X deformity to his daughters. The male will only pass his Y chromosome to his sons, leaving the expression of the X-linked disease in males to the inherited X from the mother. Women have two X chromosomes, receiving one from the mother, and one from the father.
If females express an X-linked recessive disease, it is due the inherited recessive X from both mom and dad.
