Crosses in which F₁ plants heterozygous for a given allele are crossed to generate a 3:1 phenotypic ratio in the F₂ generation are known as
A)replicate crosses.
B)reciprocal crosses.
C)test crosses.
D)monohybrid crosses.
E)dihybrid crosses.

Question

Quizplus · Accepted Answer

This type of cross is known as a monohybrid cross, which involves the study of inheritance of a single trait. When the F₁ plants are heterozygous for a specific allele, the resulting F₂ generation should show a 3:1 phenotypic ratio, with three individuals displaying the dominant trait and one displaying the recessive trait.
