Suppose 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 couple in whom each maternal meiosis is followed by imprinting of this gene have children. What can we expect as a likely outcome?
A) All sons but no daughters will bear their mother's imprinting pattern.
B) All daughters but no sons will bear their mother's imprinting pattern.
C) All sons and daughters will have a 50% chance of receiving the mother's imprinting pattern.
D) All the children will bear their mother's imprinting pattern but only daughters will then pass it down.
E) Each of the children will imprint a different chromosome.
