Reproduction is defined as the production of individuals of the same species, that is the next generation of the species. There are basically two types of reproduction - asexual and sexual. Asexual reproduction involves only one parent and the offspring is genetically similar to the parent. Sexual reproduction involves two parents and the offspring has a fusion of the characteristics of both the parents.
B. Sexual reproduction requires meiosis and fertilization. I. Comparing Sexual With Asexual Reproduction. A. In asexual reproduction, one parent passes a duplicate of its genes (DNA molecules) to its offÂ­spring, which can only be genetically identical clones of the parent. B. In sexual reproduction, each parent contributes one gene for each trait. 1. Genes for each trait come in slightly different forms called alleles, originally produced by mutations. 2. Meiosis shuffles the alleles during gamete formation, and fertilization produces offspring with unique combinations of alleles.
