When a pure bred, red flower -producing plant of genotype RR is crossed with pure bred , white flowers-producing plant of genotype rr,all the $F_{1}$ plants produced pink flowers If all the plant in each generation from $F_{1}$ to $F_{6}$ are selfed, what will be the percentage of plants with red and white flowers in the final population of plants with red and white flowers in the final population consisting of a large number of individuals? (Consider that flowers colour has no effect on reproduction and survival.)

Solution

The correct option is A $3 - 4$
R r
R RR Rr
r Rr rr
RR (Purebred red flower producing plant) x rr (Purebred white flower producing plant) produce Rr (Pink flower producing plant)
When selfing is done,
RR is produced, which produce the Purebred red flower.
Rr is produced, which produce a pink flower.
rr is produced, which produce a Purebred white flower.
Thus, the correct answer is '3 - 4.'
