Question

You cross an AbC haploid genotype with an aBc haploid genotype and obtain the following haploid progeny:
ABC 0, ABc 100, AbC 0, Abc 100, aBC 100, aBc 0, abC 100, abc 0
Are A and B loci in linkage equilibrium with each other?
Are A and C loci in inkage equilibrium with each other?
Are B and C loci in linkage equilibrium with each other?
What can you say about the genetic linkage between A, B and C loci (compare in words, each ocus to every other locus)?
Can you give another explanation, other than genetic linkage for the observed pattern (why some genotypes are not found at all?

Explanation / Answer

a) no

b) yes

c) yes

d) Yes given that no crossing over occurs between A and C loci, thus resulting in limited offspring genotypes

e) Aside from genetic linkage, it is possible that some of the offspring that could have been the other genotypes did not survive, thus there is no evidence of that genotype occuring.
