10.1 Meiosis Flashcards
Homologous Chromosomes
Chromosomes that make up a pair, one chromosome from each parent (p. 270)
Gene
Functional unit that controls inherited trait expression that is passed on from one generation to another generation (p. 270)
Gametes
Sex cells that have half the number of chromosomes(p. 271)
Haploid
Cell with n number of chromosomes (p. 271)
Fertilization
The process by which one haploid gamete combines with another haploid gamete (p. 271)
Diploid
Cell that contains 2n number of chromosomes (p. 271)
Meiosis
Reduction division process, occurring only in reproductive cells, in which one diploid (2n) cell produces four haploid (n) cells that are not genetically identical (p. 271)
Crossing over
The process by which chromosomal segments are exchanged between a pair of homologous chromosomes (p. 272)
