In a haploid organism, the two loci C and D are 8 m.u. apart. When Cd is crossed with cD meiosis occurs, producing haploid spores. Since the two genes are 8 m.u. apart, the percentage of recombinants would be 8% and the percentage of parental genotypes would be 92%. Each parental genotype would be 46%.
The proportion of the progeny classes would be:
a) C D:
Since, the percentage of recombinants is 8%; the proportion of this genotype would be 4%.
b) c d:
Since, the percentage of recombinants is 8%; the proportion of this genotype would be 4%.
c) C d:
Since, the percentage of parental genotypes is 92%; the proportion of this genotype would be 46%.
d) All recombinants:
Since, the distance between the two genes is 8 m.u; the recombination percentage is also 8%.
