NAMEill~y S'c otL Question 1. 5 POINTS, In corn, green seedling color is the phenotype of a dominant allele G. The recessive allele g results in no green color. Homozygous recessive gg corn seedlings can be either virescent-white or yellow, depending on the allele of another gene: the recessive y allele is associated with yellow seedlings, while the dominant Y allele is associated with virescent-white seedlings. In green seedlings, the phenotype is the same (green) no matter what alleles of the Y gene are present. fr' t I~ .(l.)~ A) 2 points You cross a pure-breeding GGyy strain of corn with a hybrid GgYy plant (PARENT generation). Draw a Punnet Square showing the gametes produced by each parent in this cross, and Ihow they combine to form the genotypes of the possible progeny (F1 GENERATION).
