Gene mapping using the Three-point Testcross a) Given the following alleles that control seed traits: W = wrinkled G = green R = round w = smooth g = yellow r = oval b) Results of a cross with a triple heterozygote revealed the following phenotypes: 30 smooth yellow round 4 smooth green round 958 wrinkled green round 2 wrinkled yellow oval 18 wrinkled yellow round 946 smooth yellow oval 16 smooth green oval 26 wrinkled green oval c) Determine the order of the genes and the distance between them in centiMorgan (cM). Construct a gene map to show your results. TIP: Based on the phenotypes, determine the alleles in the gametes
Gene mapping using the Three-point Testcross
a) Given the following alleles that control seed traits:
W = wrinkled G = green R = round
w = smooth g = yellow r = oval
b) Results of a cross with a triple heterozygote revealed the following
30 smooth yellow round
4 smooth green round
958 wrinkled green round
2 wrinkled yellow oval
18 wrinkled yellow round
946 smooth yellow oval
16 smooth green oval
26 wrinkled green oval
c) Determine the order of the genes and the distance between them in centiMorgan (cM).
