Question 23 :
When a pure bred, red flower -producing plant of genotype RR is crossed with pure bred , white flowers-producingplantof 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?
