Sexual Reproduction Flashcards
Haploid
A cell that contains only a single set of chromosomes and only a single set of genes
Homologous
Chromosomes that have a corresponding chromosome from the opposite sex parent
Diploid
A cell that contains both sets of homologous chromosomes
Meiosis
The number of chromosomes per cell is cut in half through the separation of homologous chromosomes on a diploid cell
Gametes
Specialized sex cell
Crossing over
Homologous chromosomes exchange portions of their chromatids
Gametogenesis

Spermatogenesis
Production of sperm
Oogenesis
Production of an egg
Polar body
Bud off from an oocyte
Zygote
Cell resulting from fertilization
Fertilization
Fusion of the sperm cell and the egg cell
Diploid
