10 A red-fruited tomato plant (which is dominant when crossed with a yellow-fruited one, produces of the progeny about half of which are red-fruited and half which are yellow fruited. What are the genotypes Purple flowers are dominant to white flowers in the Jimsonweed plant.

Suppose a women who can roll her tongue has children with a man who cannot roll his tongue. Their first child cannot roll his tongue. What does this tell us about the genotype of the woman?Explanation / Answer
10).
Assume that the gene coding for red fruits is R and the gene coding for yellow fruits is ; R is dominant over r. It is given that half of the fruits are red and the other half are brown.
Rr* rr ------> Rr (1/2, red), rr (1/2, brown)
The genotype of red fruit is Rr and the genotype of brown fruit is, rr.
