Introduction Flashcards
Gametogenesis the production of gametes occurs in ____.
Gonads
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.
False. Somatic - diploid; mature gametes - haploid
The reduction in chromosomal number during gametogenesis is achieved by what process?
Meiotic cell division
What process restores the diploid number in the fertilized egg?
Fertilization/fusion of sperm and egg
Uniqueness of each gamete produced during gametogenesis is achieve through what processes?
Random segregation of maternal and paternal homologues
Recombination during the prophase of the first meiotic division
This process involves the exchange of DNA between maternal and paternal chromosomes.
Recombination
T/F. Meiotic cell division is found only in the gonads and is thus less readily studies than mitosis.
True.
T/F. Eggs are more accessible than sperm and therefore most human information relates to female meiosis.
False. Sperm - more accessible; most human information relates to male meiosis.
Much of the prophase of female meiosis is completed in ____ and thus can only be studies in the fetus.
embryonic development
