In Certain Plants Tall Is Dominant

A 1 B 12 C 14 D 16 E 0 Answer.

In certain plants tall is dominant. AA AA Aa Aa. Lets look at a Punnett square for this cross. A heterozygous plant Aa is crossed with a homozygous tall plant AA.

Each of the offspring has one T allele so they are all tall plants. The textbook says the answer to this question is 12 but I can only get 0. Two plants both heterozygous for both genes are crossed.

If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short. Determine the probable genotypic and phenotypic ratios resulting from this cross. Mendel determined that the purple and white flower colors were the.

A heterozygous plant with yellow fruit is crossed with a plant with white fruit. If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short. If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short.

11 A dwarf red snapdragon is crossed with a plant homozygous for tallness and white flowers. Assume tall T is completely dominant to dwarf t in a certain species of plant. The phenotype for a pea plant with the genotype TtYy would be.

Predict the genotypic and phenotypic ratios of the offspring for a heterozygous tall stemmed homozygous wrinkled seeded plant and a heterozygous tall stemmed homozygous round seeded plant. If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short. In pea plants tallness T is dominant to shortness t and red flower color R is dominant to white r.
