Question

Quizplus · Accepted Answer

At fertilization, the sperm and egg unite to form a zygote, which contains the complete set of genetic instructions from both parents. The blastocyst is a later stage of embryonic development, after the zygote has undergone several rounds of cell division. The genome is the complete set of genes that an organism inherits from its parents. The embryo is a later stage of development, after the zygote has begun to differentiate into different types of cells. Therefore, the best choice is A) zygote.
