Chromosome number Definition, Haploid, & Diploid

WebFertilization and meiosis alternate in sexual life cycles. What happens between these two events depends on the organism’s “reproductive strategy.” The process of meiosis reduces the chromosome number by half. Fertilization, the joining of two haploid gametes, restores the diploid condition. Webb The species has 16 sets of chromosomes per cell. c The species is diploid with 32 chromosomes per cell. d During the S phase of the cell cycle there will be 32 separate chromosomes. e Each cell has 8 homologous pairs. e In animals, meiosis results in gametes, and fertilization results in a spores. b sporophytes. c clones. d zygotes.
