Question

Imagine that a gene on human chromosome 18 can be imprinted in a given pattern in a female parent but not in a male parent. A woman in whom each maternal meiosis is following by imprinting of this gene marries and has children. What is the expected outcome?

Answer 1

Answer:

All the children will bear their mother's imprinting pattern but only daughters will then pass it down

Explanation:

The imprinting patterns on the gene only occurs to female parent after each maternal meiosis. It will be maternally inherited that is, it can be passed down from the mother to the offsprings.

Therefore, when the woman gets married and has children, all the children including the males (sons) will bear the imprinting pattern. However , only the females (daughters) will be able to pass it down.
