To determine if the genotype of a pea plant with a dominant phenotype is homozygous dominant or heterozygous, a ______ may be completed.

The height of pea plants is controlled by a single gene with two alleles: a dominant tall allele (T) and a recessive short allele (t). Which of the following is the genotype of a homozygous dominant pea plant?TtttTXTT 4

In the garden peas of one pair of alleles controls the height of theplant and a second pair of alleles controls flower colour. Theallele for tall (T) is dominant to the allele for dwarf (t) and theallele for purple flower colour (P) is dominant to the allele forwhite (p).a. A tall plant with purple flowers crossed with a dwarf plant withwhite flowers produced 50% tall, purple and 50% tall, whiteprogeny. What is the genotype of the parents?b. A tall plant with white flowers crossed with a dwarf plant withpurple flowers produced 25% tall purple, 25% tall white, 25%dwarf purple and 25% dwarf white individuals. What is thegenotype of the parents?

A pea plant is heterozygous for the genes for seed form (Rr) and seed color (Gg). It is crossed with a pea plant of the genotype rrgg. How many of the 60 offspring of this mating are predicted to show the dominant trait for both genes? (The genes are not linked.)Multiple Choice5033150            30

Multiple Choice QuestionIf a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is Blank______.Multiple choice question.dominant over dwarf plantrecessive when compared to dwarf plantnon-blending with dwarf plant

In a test cross, a homozygous recessive pea plant with green seeds is mated with a yellow-seeded plant of unknown genotype. If all the progeny have yellow seeds, then the genotype of the yellow-seeded plant is
