Mendelian Genetics - biology questions?

1. Choose all: If you cross a true-breeding pea plant with green pods, and a true-breeding pea plant with yellow pods:

A. If a plant has the phenotype of yellow pods, its genotype is always gg.
B. In the parental (P) generation, the plant with green pods can produce gametes with only the G allele for pod color.
C. In the parental (P) generation, the plant with green pods has the genotype gg.
D. Plants with green pods in the F1 generation can produce gametes with either the G allele or the g allele.

2. Choose all. The blending theory and particulate theory of inheritance both attempt to explain how biological traits are transferred from one generation to the next. Which of the following statements is correct about this topic?

A. The blending theory would have been supported if Mendel had gotten lavender (light purple) flowers when he crossed purple with white.
B. The blending theory would have been supported if the traits Mendel called "recessive", such as green seeds or yellow pods, disappeared after the P generation and were not seen again in the F2 or subsequent generations.
C. The particulate theory is supported by the fact that although a recessive trait disappears in the F1 generation, it reappears in the F2.
D. The particulate theory and Mendel's first law are supported by the 3:1 ratio of phenotypes in the F2 generation.

3. Choose all. A true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant; tall is dominant.

A. The genotype for the dwarf P generation plant is "dd".
B. The tall plant in the P generation is homozygous dominant.
C. All of the F1 generation will be intermediate height (halfway between tall and dwarf).
D. On average, 1/4 of the F1 generation will be dwarf.
