In a hypothetical organism, green fur color is dominant over blue, and fur color

Question

In a hypothetical organism, green fur color is dominant over blue, and fur color is determined by a single gene (G-dominant allele, g-recessive allele) For the following crosses: Blue X pure line green Blue x heterozygous green Heterozygous green x heterozygous green What gametes will be produced and what will be the genotypes and phenotypes of the offspring (answer for each section A, B, C)? What is meant by the P, Fl, F2 generations of cross A above? How many different genes, alleles, phenotypes, and genotypes are involved?

Explanation / Answer

1. A). ggxGG= all gametes will be Gg B). ggxGg= 1/2 of gametes will be heterozygous for the trait (Gg) the other half will be homozygous reccessive (gg) C). GgxGg= 1/4 will be GG, 1/2 will be Gg and 1/4 will be gg -use the punnet square method for determining the outcomes. 2. P stands for parental, the two species producing the offspring. F1 is the first filial generation or the offspring of the parents. F2, therefore, is the offspring of the F1 generation 3. there are 4 alleles, 2 alleles for each phenotype; there are only two phenotypes (brown and green fur) and there are 3 different kinds of genotypes that can occur with these crosses (GG, Gg, gg)
