FSH and LH directly promote development of the uterine endometrium
mitosis
labia majora
they have the same number of chromosomes
stimulates mammary gland development
regression of the corpus luteum and a decrease in ovarian progesterone secretion
Each spermatid forms two sperm.
serves as a passageway for the primary oocyte
in oogenesis, one mature ovum is produced, and in spermatogenesis four mature sperm are produced from the parent cell
the seminal glands
The hormones cause the woman's body to mimic the activities of a pregnancy and disrupt the ovarian cycle, preventing ovulation.
It is a significant source of genetic variation only during meiosis I.
GnRH
involves FSH and LH release
The narrow portion of the uterus near the cervix is the most typical site of fertilization.

uterine tubes
The sister chromatids are separated from each other.
involves a kind of cell division limited to the gametes
a parasympathetic reflex
Rebuilding the endometrium is under the control of prolactin.
twice the diploid number, and with every succeeding generation, the chromosome number would continue to double and normal development could not occur
