WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse … WebMeiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one …

WebIn meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and ...
WebMitosis is the division of a single cell into two cells (as shown here), each with its own nucleus and the same number and kind of chromosomes as the parent cell. Meiosis occurs when a single cell divides twice to produce four cells containing half the original amount of genetic information. Juhari Muhade/Getty Images.
