Additional question 5d A, B, and C are independently assorting Mendelian genes controlling the production of a purple pigment. The alternate alleles that give abnormal tunctioning of these genes are a, b, and c. A purple individual of genotype AA BBCC was crossed with a yellow individual of genotype aa bb cc to produce a purple F1. F xF1 crosses were perfonned and the F2 progeny where either yellow, orange, red or purple. Assume that A B. and C act in a pathway as follows yellow -oo orange rad purple What proportion of the F2 progeny will be puuple? 9/64 9/16 1/4 27/64 3/16 9 of 9 Save Submit Remalning: 2:14:00 Start: 10:40 PM 0:16 PM 2/26/2017

Solution

As F1 is purple progeny, so it should be

AaBbCc.

AaBbCc × AaBbCc - F2 progeny.

So according to the genotypes formed after this cross, 27/64 F2 progeny will be purple.

For checking the cross for F2 progeny one can use punnett square.
