Question

pea plants can have yellow seeds or green seeds. which conclusion about the meaning of y is correct if the allele combination yy is for yellow seeds?
○ yellow and dominant
○ green and recessive
○ yellow and recessive
○ green and dominant

Explanation:

In genetics, a dominant allele is represented by an uppercase letter and masks the effect of a recessive allele (lowercase). The allele combination Yy gives yellow seeds. Since Y is uppercase, it's dominant, and the phenotype (yellow) matches the allele's expression. So Y must be for yellow (the expressed trait) and dominant.

Answer:

yellow and dominant
