In pea plants, the allele T encodes for tall plants, while the allele t encodes for dwarf plants. If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant what are the expected genotypes of the offspring?

In peas, the allele for tall plants, T is dominant over the allele for short plants, t. A farmer growing pea plants for seed would like to obtain parental plant stock that is homozygous (TT) for the tall plant allele (he prefers tall plants). 1. The farmer obtains a tall pea plant. What are the two possible genotypes for this plant? 2. To figure out which of the above genotypes the tall plant is carrying, the farmer carries out a test cross between the tall plant and a pea plant with the short phenotype. What is the genotype of the short plant?

The allele for tall pea plants is dominant over the allele for short pea plants. If two heterozygous plants are crossed, what will the genotypic and phenotypic ratios be

In pea plants, the dominant allele T gives a tall phenotype while the recessive allele t has a dwarf phenotype. Draw the Punnett square by clicking on and placing the correct capital or lowercase letter combination in the boxes. In this example, eggs and sperm can be placed on either top or side. Tt x Tt What is the genotype ratio? What is the phenotype ratio?
