Question

Give the genotype(s) of Y1. Remember that Y1 is pure-breeding and that the two genes interact by dominant suppression. Assume that a dominant allele in gene A suppresses gene B

Check all that apply.

Two pure-breeding strains of summer squash producing yellow fruit, Y1 and Y2, are each crossed to a pure-breeding strain of summer squash producing green fruit, GI , and to one another. The following results are obtained Cross FP Y1 (yellow) xG1 Al (green) yellow green Y2 (yellow) xG1A9 (green) green: green yellow 13 Y1 (yellow) xY2 All (yellow) 1yellow. 16 16 yellow green

Explanation / Answer

as its a dominant suppression wherein A is dominant over the dominant allele B, For Y1 to produce yellow color, it must have atleast one A.
