One character in peas that mendel studied was yellow versus green seeds. a cross between a homozygous yellow line (gg) and a homozygous green line (gg) will result in f1 plants that are heterozygous (gg) for this trait and produce yellow seeds. cross between homozygous yellow and green pea plants when an f1 plant undergoes meiosis, what gamete types will it produce, and in what proportions? use your understanding of mendel’s law of segregation to label each gamete possibility as "correct" or "incorrect."
