Detailed explanation-1: -The # of recombinant offspring / total # of offspring x 100% = recombination frequency.
Detailed explanation-2: -Recombination increases genotypic diversity but does not affect gene (allelic) diversity. Recombination in eukaryotes occurs primarily by meiosis during sexual reproduction; additional recombination may also occur by nonmeiotic mechanisms.
Detailed explanation-3: -If meiosis results in recombination, the products are said to have a recombinant genotype. On the other hand, if no recombination occurs during meiosis, the products have their original combinations and are said to have a non-recombinant, or parental genotype.
Detailed explanation-4: -Thus, recombinant gametes produced by the dihybrid will have the genotypes ab or AB, and non-recombinant (i.e. parental) gametes will have the genotypes aB or Ab.
