Question

Quizplus · Accepted Answer

The single cell resulting from the union of sperm and egg cells is called a zygote. This is the first stage of development for a new organism. A is incorrect because sex chromosomes are the chromosomes that determine an organism's sex, and they are not formed until later in development. C is incorrect because gametes are the sperm and egg cells themselves, not the result of their union. D is incorrect because autosomes are the non-sex chromosomes, and again, they are not formed until later in development.
