Meiosis and sexual reproduction review
WebIn sexual reproduction, through the process of meiosis, a parent's alleles end up in its gametes; either egg or sperm. Only one allele from each allele pair ends up in a gamete. For example, in the pea plant, each gamete would contain either \ ( \underline {P} \) or \ ( p \), but not both. How many types of alloles does each parent possess in ...
