After fertilization,a zygote rapidly divides to produce small,genetically identical cells known as:
A)pronuclei.
B)blastomeres.
C)trophoblasts.
D)centromeres.

Question

Quizplus · Accepted Answer

After fertilization, the zygote undergoes a series of rapid cell divisions called cleavage. Each division produces smaller and smaller cells called blastomeres, which eventually form a hollow ball of cells known as the blastocyst. Pronuclei are the haploid nuclei of the sperm and egg before they fuse, trophoblasts are cells that form the outer layer of the blastocyst and give rise to the placenta, and centromeres are structures that help separate chromosomes during cell division.
