This is the diploid chromosome condition and the paired chromosomes are called homologous. Meiosis transforms a diploid cell into four haploid granddaughter cells, each having a single copy of each chromosome. The process helps increase the genetic diversity of a species.
Sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other. This occurs for a number of reasons. 1  When homologous chromosomes pair up during meiosis I, crossing-over can occur. Sexual reproduction involves two parents and produces offspring that are genetically unique. 2  During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. 3  Meiosis is the type of cell division that produces gametes.
