BISC 220 Prep Exam Questions With 100%
Verified Answers!!
what does each gamete contain?
23 chromosomes - half the number of chromosomes in a normal cell (haploid)
what happens when an egg and sperm fuse at fertilization?
they form a zygote with a full set of 46 chromosomes (diploid)
Meiosis
Cell division that produces reproductive cells in sexually reproducing organisms. Divides
precursor diploid cell into haploid
meiosis I
Homologous chromosomes separate, each cell has two copies of one of each homologue
(haploid with duplicated chromosomes)
Meiosis II
sister chromatids separate, each gamete is haploid with unduplicated chromosomes
genetic recombination
The regrouping of genes in an offspring that results in a genetic makeup that is different
from that of the parents.
male external reproductive organs
scrotum and penis
male internal reproductive organs
, gonads, accessory glands, ducts
male reproductive system function
production and delivery of sperm, secretion of sex hormones
sperm pathway
Seminiferous tubules, Epididymis, Vas Deferens, Ejaculatory Duct, Nothing, Urethra,
Penis (SEVEN UP)
male sex accessories
epididymis, vas deferens, seminal vesicles, ejaculatory duct, prostate, bulbourethral (Cowper's)
glands, urethra and penis
male urethra parts
prostatic, bulbous, and penile
vas deferens
tube that carries sperm from the epididymis to the urethra
vas deferens and seminal vesicle
merger forms the ejaculatory duct, produce seminal fluid, which aids in ion/water transfer
and maturation of spermatozoa
prostate gland
A gland in males that contributes to the seminal fluid. Surrounds upper portion of urethra.
what does prostate gland produce
citrate and alkaline secretions that activate sperm and reduce the acidity of the female
reproductive tract
age-related prostate enlargement
begins at middle age, increased mass may restrict urine fow
prostate cancer
