Gamete recombination
Webrecombination, in genetics, primary mechanism through which variation is introduced into populations. Recombination takes place during meiosis, when maternal and paternal genes are regrouped in the formation of gametes (sex cells). Recombination occurs randomly in nature as a normal event of meiosis and is enhanced by the phenomenon of crossing … WebIf the genes are closely linked, a gamete is much more likely to contain (A1,B1) or (A2,B2) ‐“non‐recombinants.” If there is recombination, a gamete contains (A1, B2) or (A2,B1), but these two possibilities are less likely. (In contrast Mendel’s second law says
