Biology 2: Reproduction Flashcards
p53
tumor suppressor protein
controls the G1/S and G2/M cell cycle checkpoint

Mendel’s second law of independent assortment
states that the inheritance of one allele has no effect on the likelihood of inheriting certain alleles for other genes
Mendel’s first law of segregation
homologous pairs separate and are pulled to opposite poles of the cell
what are the two functional components of the testes?
seminiferous tubules
interstitial cells of Leydig
seminiferous tubules
highly coiled tubules in the testes
site of sperm production

sertoli cells
cells within the seminferous tubules
nourish sperm
cells of Leydig
cells in the testes which secrete testoseterone and other male hormones (androgens)

scrotum
external pouch that hangs below the penis and maintains a temp lower than body temp
location of the testes
pathway of sperm through the male reproductive system
Seminiferous tubules -> Epididymis -> Vas deferens -> Ejaculatory duct -> Urethra -> Penis

SEVE**(N) **UP
which glands produce seminal fluid?
seminal vesicles
prostrate gland
bulbourethral gland
seminal vesicles
contribute fructose to nourish sperm and produce alkaline fluid

prostate gland
gland in the male reproductive tract that only serves to produce alkaline fluid for seminal fluid
bulbourethal (Cowper’s) gland
produces a clear viscous fluid that cleans out any remnants of urine and lubricates the urethra during sexual arousal

____ + ____ = semen?
seminal fluid + sperm
