Question

Which of the following trait shows transmission from carrier female to male progeny? (1)Autosomal dominant(2) X-linked recessive (3)Y-linked recessive (4)X-linked dominant

Answer 1

Answer:

2. X-linked recessive

Explanation:

Transmission of genes from carrier female (mother) to male progeny (son) is seen in X-linked recessive inheritance. X-linked because it occurs in the X-chromosome of the mother. The presence of a single recessive gene does not cause the disease, thus it is a recessive trait. Hence, the male progeny (son) will have a disease.

Answer 2

The correct option is (2) X-linked recessive.

In humans, the inheritance of X-linked recessive characteristics follows a distinct three-point pattern.

• The first is that while fathers give their kids Y chromosomes, they cannot pass on X-linked recessive traits to them.
• This means that males with an inherited X-linked recessive condition will inherit it from their mothers' X chromosome.
• Second, males are more likely than females to have X-linked recessive characteristics.

Concept of X-linked recessive

• Genetic problems related with mutations in genes on the X chromosome are referred to as X-linked recessive inheritance.
• Because he only has one X chromosome, a male having such a mutation will be affected.
• A girl with a gene mutation on one X chromosome but a normal gene on the other is usually unharmed.
