Question

(i) You are given axial pea flowers with violet colour whose genotypes are unknown. How would you find the genotype of these plants ? Explain with the help of cross. (ii) Explain Haplodiploidy in honey-bees.

In a pea plant (Pisum sativum) green pod colour is dominant over yellow pod colour. The expected ratio of phenotypes of the first generation offspring in a cross between both the parents with heterozygous green pod colour will be :
