A geneticists crosses two strains of yeast. One with yellow colonies 3 resistant to an antifungal drug, the other-with white colonies and sensitive to the drug, She analyses 100 asci by growing four from each. (One from each). She finds 47 asci that produces two types of colonies yellow, resistant and white, sensitive, 48 asci that produce yellow sensitive 3 white resistant colonies, and, asci that produce all four possible combinations of color and resistance.

Solution

No, the genes are not linked.This can be proved from the above results with the point that 5 asci produce all the four possible combinations of color and resistance.Also there are combinations of yellow and sensitive and white and drug resistant colonies that are not parental combinations but recombinant ones.This proves that the genes for color and resistance assort independently and are not linked.
