Q

T/F. In gametogenesis, somatic haploid chromosomal complement is halved to the diploid number of a mature gamete in such a way as to ensure that each gamete contains one member of each pair of chromosomes.

A

False. Somatic - diploid; mature gametes - haploid

Q

T/F. Meiotic cell division is found only in the gonads and is thus less readily studies than mitosis.

Q

T/F. Eggs are more accessible than sperm and therefore most human information relates to female meiosis.

A

False. Sperm - more accessible; most human information relates to male meiosis.
