If a plant homozygous for liguleless and green leaves is crossed to one homozygous for non-green with ligules, predict the proportion of F₂ progeny with the genotype Llgg.

Question

Quizplus · Accepted Answer

The F1 generation will be heterozygous for both traits (LlGg). In the F2 generation, the genotype Llgg can be obtained by crossing LlGg x LlGg, which gives a 1/4 chance for Ll and a 1/4 chance for gg, resulting in a 1/16 chance for Llgg. However, since the question asks for the proportion of Llgg, we consider the 1/4 chance for Ll and 1/2 chance for gg, giving 1/8.
