Chromosome reproduction

WebMany sexually reproducing organisms are diploid. Diploid organisms have two sets of chromosomes in each cell. These chromosomes are organized into homologous pairs. In order to reproduce, diploid organisms produce gametes in the form of egg or sperm cells. These gametes are haploid. Haploid gametes have only one set of chromosomes. WebIn meiosis, DNA is replicated to produce a total of four copies of each chromosome. This is followed by two cell divisions to generate haploid gametes. After the DNA is replicated in meiosis, the homologous …

WebSexual reproduction requires fertilization, a union of two cells from two individual organisms. If those two cells each contain one set of chromosomes, then the resulting cell contains two sets of chromosomes. The number of sets of chromosomes in a cell is called its ploidy level. Haploid cells contain one set of chromosomes. WebThus, mitosis is one way§ that asexual reproduction can occur, but only when the cell is an entire organism. In contrast, meiosis is a method for producing new cells with half the number of chromosomes that were found in the mother cell. (Genetic recombination also takes place during meiosis.)
