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 Web1.Genetic recombination is possible because of ________ during or after meiosis. o independent assortment. o crossing ove. o fertilization with a nonrelated gamete. o All of these are correct. 2.Sister chromatids are. o genetically different and attached to each other. o genetically identical and attached to each other.

Web20 hours ago · Meiosis is the specialized cell cycle used to generate genetic diversity and reduce the genome copy number in gametes. Successful meiosis requires homologous chromosomes to pair and recombine to form crossovers, which are necessary for proper chromosome segregation. 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).
