Sexual Reproduction & Meiosis A. Sexual Reproduction 1. Asexual reproduction needs only one parent 2. Sexual reproduction needs two sex cells a. Sperm--male sex cell b. Egg--female sex cell B. Importance of Sex Cells 1. In body cells, chromosomes found in pairs a. Pairs form because chro...
Mitosis and meiosis, respectively分别, make simple cell division and sexual reproduction possible. Each means of passing on hereditary 遗传 information has advantages. In asexual 无性的 reproduction the parent organism生物体 gives rise to offspring 后代that are genetic clones of the parent. The advant...
Meiosis, from the Greek wordmeioun, meaning "to make small," refers to the specialized process by which germ cells divide to producegametes. Because thechromosomenumber of aspeciesremains the same from one generation to the next, the chromosome number of germ cells must be reduced by half du...

During sexual reproduction, both male and female organisms make gametes. The process of making gametes is called meiosis and creates four genetically unique, haploid sex cells, like sperm and eggs. This means that the genetic makeup of both the sperm and eggs is different from the genetic make...
Meiosis Making Sperm and Eggs Meiosis occurs in sexual reproduction when a diploid (2n) germ cell produces 4 haploid (1n) daughter cells that can mature to become gametes (sperm or egg) Goal of Meiosis Goal: Reduce genetic material by 1/2. from mom from dad child meiosis reduces genetic ...

In dipteran flies29and lepidopterans30, chromosomal crossovers and thus recombination occur only in one sex, with male flies and female lepidopterans having achiasmate meiosis. A formerly autosomal neo-sex region in these species therefore immediately stops recombining after a fusion with an ancestral...
