In corn, having ligules (L) is dominant to liguleless (l) , and green leaves (G) is dominant to white leaves (g) .
-If a pure-breeding liguleless plant with green leaves is crossed to pure-breeding plant with ligules and white leaves, predict the proportion of F₂ progeny with the genotype Ll gg.

Question

Quizplus · Accepted Answer

The cross between a pure-breeding liguleless, green-leaved plant (ll GG) and a pure-breeding plant with ligules and white leaves (LL gg) produces F1 offspring that are all heterozygous for both traits (Ll Gg). When these F1 plants are crossed (Ll Gg x Ll Gg), the genotype Ll gg (ligules present, white leaves) occurs with a probability of 1/2 (for Ll) multiplied by 1/4 (for gg), which equals 1/8.
