Question

# In tomato plants, red skin color (R) is dominant to yellow skin color (r). A red-skinned tomato plant was crossed with a yellow-skinned tomato plant, and the following proportion of F$$_1$$ offspring resulted: 79 red-skinned tomatoes, 68 yellow-skinned tomatoes.What were the genotypes of the P generation?

A
RR and rr
B
Rr and RR
C
Rr and Rr
D
Rr and rr
E
None of the above

Solution

## The correct option is D Rr and rrR is the gamete for red color and r is the gamete for yellow skin color. Red color is dominant to yellow color and almost equal number of red and yellow skinned tomatoes are obtained. Both these phenotypes in $$F_1$$ generation will be expressed if a cross is made between the genotypes Rr and rr as shown in the Punnett square. Thus the correct answer is option D.Biology
