Question

1. a variety of corn can produce yellow or white seeds. yellow is dominant. white is recessive. if an ear of corn contains only white corn, it must be - heterozygous dominant homozygous dominant heterozygous recessive homozygous recessive clear all

Explanation:

• In genetics, for a recessive trait (white corn in this case) to be expressed, an organism must have two copies of the recessive allele.
• A heterozygous dominant (e.g., \(Yy\)) would show the dominant trait (yellow). A homozygous dominant (\(YY\)) also shows the dominant trait. There is no such thing as heterozygous recessive (since recessive is only expressed when two recessive alleles are present). A homozygous recessive (\(yy\)) has two recessive alleles and thus shows the recessive trait (white).

Answer:

homozygous recessive
