The trait traced in this pedigree is 

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.)

A couple has $$8$$ children, all boys. What is the chance that their ninth child will be another boy?

Mutation is

The  grain colour of wheat is determine by the additive effects of two pairs of genes Accordingly the $$F_2$$ inhertance appears in the ratio of $$15$$ red ,$$1$$ white  the fifteen red appear in different shades in the ratio of
