Let us first decide the order of genes. The genotype with maximum number of individuals is parental followed by single cross overs and then double cross overs. The genotypes with minimum number of individuals are the ones with double cross overs. number of individuals genotypes type of individual 2021 G R L Parental 1987 G+ R+ L+ Parental 600 G+ R L+ single cross over between R and G 444 G R+ L single cross over between R and G 125 GR L+ single cross over between L and G 122 G+ R+ L single cross over between L and G 7 G+ R L Double cross overs 1 G R+ L+ Double cross overs TOTAL=5307 The double cross overs are in lowest frequency and moves the middle gene. To decide the correct order of genes it is important to decide the middle allele others can vary. Here, in double cross overs G allele is different from parental ones. Hence, G will be in the middle.Now, calculate the distance between the genes. Distance between genes =number of single cross overs + number of double cross overs total progeny×100total progeny=5307Distance between R and G=600+444+7+15307×100 =10525307×100 =0.198×100 =19.8cMDistance between L and G=125+122+7+15307×100 =2555307×100 =0.048×100 =4.8cMFinal gene map
