To solve the problem of how a cross between two tall pea plants can produce some dwarf offspring, we can use a Punnett square to illustrate the genetic inheritance involved. Here’s a step-by-step solution: ### Step 1: Determine the Genotypes of the Parents In pea plants, the allele for tallness (T) is dominant over the allele for dwarfness (t). Since we are crossing two tall plants that can still produce dwarf offspring, we can assume that both parents are heterozygous for the trait. Thus, the genotypes of the parents are: - Parent 1: Tt (tall) - Parent 2: Tt (tall) ### Step 2: Determine the Gametes ...
