4.Principles of Inheritance and Variation
medium
When Mendel crossed true breeding white-flowered strain of peas with a true breeding red-flowered strain, individuals in the $F_2$ represented
A
White-flowered plants
B
Red-flowered plants
C
Red-flowered and white-flowered plants in the ratio $3 : 1$
D
Red and white-flowered individuals in the ratio $1 : 1$
Solution
(c) Red flowered and white flowered plants in the ratio $3 : 1$; parents are with the genotype $RR$ and $rr$, the $F_1$ individuals are $Rr$, and they in $F_2$ generation will produce red and white flowered plants in ratio of $3 : 1.$
