In a given cross between two heterozygote AaBbCcDdEe we get in first generation following
Probability of getting Aa = 1/2
Probability of getting AA is = 1/4
Probability of getting BB is = 1/4
Probability of getting Bb is = 1/2
Probability of getting CC is = 1/4
Probability of getting Cc is = 1/2
Probability of getting dd is 1/4
Probability of getting ee is 1/4
Probability of getting phenotype ABCde or genotype A_B_C_ddee can be calculated by forked line method
In which probability of getting :
- AABBCCddee will be 1/4x1/4x1/4x1/4x2/4= (1/4)5
- AaBbCcddee will be 1/2x1/2x1/2x1/4x1/4= (1/2)3 (1/4)2
- Similarly for other genotypes individual probability can be multiplied as given above and particular genotype can be arrived at .

In a cross involving independently assorting loci, the cross BBYY x bbyy (assume "B" and "Y" are dominant to "b" and "y," respectively) will yield all dihybrid offspring. When those offpspring are crossed, the result is usually a 9:3:3:1 phenotypic ratio. But what if the locus "B" and "Y" did not sort independently (i.e., they were linked, at least partially)? It would mean "BY" and "by" are now more likely. How would this specifically affect the expected 9:3:3:1 ratio? To...

44. In Nicotiana tabacum, there are two independently-assorting gene loci that influence the appearance of the yellow burley character, i.e. A and B. When both loci are homozygous for their recessive alleles, i.e. aabb, the plant is yellow. When a dominant allele, i.e. A or B, is present at either locus, the plant is green. (a) If a cross were made between a homozygous green strain monosomic for one of these chromosomes (ABB) and a disomic yellow strain (aabb), what...

1. At least 3 independently assorting loci are known to govern coat color in mice. The genotype C- will allow pigment to be produced by 2 other genes. The cc genotype does not allow pigment production resulting in albino mice. The striped “agouti” hair pattern depends on the genotype A- and the aa genotype is nonagouti. Finally, the color of the pigment may be black (B-) or brown (bb). Five different coat colors may be produced by the action of...
