Unformatted text preview: When this "individual" makes gametes, we can say that recombination occurs with a frequency (or probability) " r ". Thus recombination does not occur with a probability (1-r) . When recombination does not occur the gametes produced will be A B and a b (note only one letter is used at each locus because gametes are haploid); when recombination does occur the gametes will be A b and a B . (see figure 2.7, pg. 34). If the loci were on separate chromosomes (unlinked) and we were "given" a gamete with the "A" allele, 1/2 of the gametes would be AB and 1/2 would be Ab (the under score is omitted as a shorthand notation). If we were "given" a gamete with the "a" allele, 1/2 the gametes would be ab and 1/2 would be aB. These four gametes would be in the relative proportions 1:1:1:1....
