WebStep 3: Determine recombinant gamete frequency. Once all six recombinant gametes have been classified, the total number of crossovers between the three loci can be added up and crossover percentage determined between each pair of loci. This number will reflect gene distance but one more step is needed to complete the process. WebUse a chi-square test to determine if the observed numbers of progeny fit the number expected with independent assortment. arrow_forward How many kinds of gametes will be expected from an individual with the genotype ppccTTRr?
