Q

Process by which a spermatocyte reduces the number of chromosomes in its nucleus to 23, or half the normal number, to create gametes.

A

meiosis

35
Q

Process by which most body cells reproduce. The 46 chromosomes in the nucleus duplicate, and then split, creating two identical cells, each with 46 chromosomes.

A

mitosis

36
Q

Period of time when FSH and LH from the anterior pituitary gland first begin to stimulate the testes. Testosterone causes the male sexual characteristics to develop, and there is a growth spurt.

A

puberty
