Question
l he above are true Your answer is INCORRECT Two loci exist on different chromosomes, the A locus is on chromosome two. The relative fitness of the different genotypes is shown in the picture, as is the location of the loci on each chromosome. Next to this, the genotypes and their relative fitness is provided in column form. Given this information, what can you say is true? one whereas the B locus is on Relative Fitness of Different Genotypes Genotype fitness AABB 1.0 AABb 1.0 AAbb 1.0 AaBB 0.5 AaBb 0.5 Aabb 0.5 aaBB 1.0 aaBb 1.0 aabb 1.0 AB aB 0.5 o0.5 0.5 o.5 ab 0.5 0.5 0.5 0.5 0 1 0 2 a) Epistasis for fitness between the A and B loci will produce linkage disequilibrium between thenm b)Hitchhiking between the A and B loci produces linkage disequilibrium between them. c) C Physical proximity between the A and B loci produces linkage disequlibrium between them d) L The fitness effects of the A and B loci are independent, in other words, there is no epistasis for fitnessExplanation / Answer
Answer is D
genetic linkage is defined as the tendency of genes that are close together on a chromosome to be inherited together,
In the given question, since genes A and B on 2 separate chromosomes, there is no linkage between them and hence there is no epistasis for fitness
