Question

In a situation where there is an empty egg with no fertilized DNA resulting in a 46XX karyotype, what term best describes this condition?

A. Molar pregnancy
B. Aneuploidy
C. Ectopic pregnancy
D. Hydatidiform mole

Answer 1

The condition described by an empty egg with no fertilized DNA resulting in a 46XX karyotype is known as a Hydatidiform mole, which is a type of molar pregnancy.

Step-by-step explanation:

In the case of an empty egg with no fertilized DNA resulting in a 46XX karyotype, the condition is best described as a Hydatidiform mole, or molar pregnancy. This occurs when a sperm fertilizes an egg that lacks a nucleus, or when two sperm fertilize a single egg, leading to an abnormal pregnancy with no viable fetus.

The tissue that should become the placenta instead becomes an abnormal growth, often resembling a cluster of grapes. This condition can have serious health implications for the mother and requires medical treatment.
