User: You have a plant with yellow seeds, which express a dominant phenotype. How would you determine the plant's genotype?

Weegy: You should test cross with a purebread homozygous recessive plant. Because your plant is Yy (heterozygous) or YY (homozygous dominant), cross testing it with a yy will get you an answer. [ If you get all yellow phenotypes then the genotype for the plant in question will be homozygous dominant (YY) since crossing a YY with a yy will only lead you to Yy (Heterozygous) yellow plants. If you get any plants with the recessive trait then the plant in question MUST be Yy since only crossing a Yy with a yy will you get a plant that is homozygous recessive ]
