Abnormalities present in the cells that line the uterus may prevent the production of offspring by directly interfering with which process?

Answer: Implantation

Explanation:

The uterus is the main site for the implantation of the embryo. It is the place where the embryo spends 9 months in the mother.

When the male and female gamete combine they form a zygote. It gets implanted in the uterus and then there is cell division and the development of embryo takes place there only.

Any abnormalities in this region will interfere in the process of implantation.
