Question

You irradiated plants and identified four mutants that have white flowers instead of the wild type purple flowers. A complementation test was performed by crossing them in all pairwise combinations. The flower colors for the F1 progeny are given below. Based on these data, how many genes can be defined? Which mutations are allelic (in the same gene)? In some types of melons fruit color is controlled by two alleles W (white) and Y (yellow) that generate three different phenotypes: white, yellow or green melons. In a cross between a pure-breeding white melon and a pure-breeding green melon, the F2 ratio is 23 white, 7 yellow and 2 green. What mode of inheritance is this? What allele (w or tic in the biochemical pathway leading to fruit Color?

Explanation / Answer

Based on the observations of the experiment 3 genes can be defined,

Mutation 1 and 4 are the allelic mutations on same gene.
