D)Nuclear condensation

Question

Quizplus · Accepted Answer

At fertilization, the union of one mature haploid sperm with one mature haploid ovum occurs to form a diploid zygote. One sex chromosome is provided by the spermatocyte, and one is provided by the mature ovum, determining the primary or "genetic" sex of the new zygote. The nucleus increases in size and does not condense at this time. The gametes are haploid long before fertilization occurs. Changes in the acrosome of the spermatocyte and coronal cells of the ovum also occur before fertilization, not after.
