In pea plants, height is controlled by a single gene and the tall allele (T) is dominant to the short allele (t). You find a tall pea plant in your yard and cross it with a short pea plant. It gives rise to 43 tall offspring and 35 short offspring. What is the genotype of the tall parent plant? Answers: Tt tt TT

2. Mendel studied the inheritance of height in his pea plants. The F-2 generation consisted of both dwarf plants (recessive trait) and tall plants (dominant trait). a) Using Punnett squares, show how he might be able to determine if a tall plant was heterozygous (Tt) or homozygous dominant (TT) by crossing each with a dwarf plant (tt). b) Explain the results in a sentence.
