Question

Quizplus · Accepted Answer

In a monohybrid cross, the ratio of dominant to recessive phenotypes is 3:1. This means that out of every 4 seeds, 3 will display the dominant phenotype and 1 will display the recessive phenotype. Therefore, if we count 1000 seeds, we can expect 750 to display the dominant phenotype (3/4 x 1000 = 750).
