Question

The genotype of purple flowered pea plants is denoted as WW and that of white flowered pea plant as ww. When these two are crossed i) What color of flowers do you expect in their F1 progeny? ii) What will be the percentage of white flowered plants produced if F1 plants are self pollinated? iii) In what ratio would you find the genotypes WW, Ww and ww in the F2 progeny?

Answer 1

ii) 25 % flowers will be white as only homozygous (ww) will be white
Ratio of purple to white in ratio 3:1.
