In a cross between plants with purple flowers and plants with white flowers the offsprings of `F_(1)` generation all had white flowers. When the `F_(1)` generation was self-crossed, it was observed in the `F_(2)` generation that out of 100, 75 flowers were white. Make a cross and answer the following :
(i) What are the genotypes of the `F_(2)` progeny?
(ii) What is the ratio of 'White : Purple' flowers in the `F_(2)` generation?

Explanation

`{:("Monohybrid Cross"),("White Flowers Purple Flowers"),(" WW "xx" WW"),(" White Flowers"):}` (i) Genotypes of F2 progeny are : wW, Ww, ww (ii) Ratio between White : Purple flowers are : 3:1 1.
