Possible types of genotype it can form is RS , rs'.
As R and S are linked genes , it can't. assort independently.
Thus only the possibility of RS is possible with rest rs'.

Question 2 Genes a and b are linked, with 20% recombination frequency. Two pure breeding strains (the parental cross) were crossed. The F1 was then testcrossed. a+b-/a-b+ x a-b-/a-b- What were the parental strains genotypes? b. What would be the genotypes and the probability of each, among progeny of the testcross? Example: a+b+/a-b- 45% c. Is this an example of cis- or trans-linkage?

Question 5 In Drosophila, ebony body (e) and rough eyes (r) are encoded by linked autosomal recessive genes on the third chromosome and are completely linked at O map units apart. A homozygous ebony female was crossed to a homozygous rough male. The F1 were all wild ty The F1 females were crossed to ebony, rough males. Give the phenotypes and their proportions in the F2. ebony, rough 20%, wildtype 20%, ebony 30%, rough 30% ebony, rough 30%, wildtype 30%,...

You are following the inheritance of three genes: A, B and C. A and B are on the same chromosome; C is on a different chromosome from A and B (for example; A and B are on chromosome 1 and C is on chromosome 4).Which option correctly represents the genotype of an individual who is heterozygous for all three genes?What is the recombination frequency for unlinked genes (i.e., genes that sort independently)? Frequency is given as a number from 0...
