A farmer planted 300 corn kernels from a single ear, resulting in 225 tall plants and 75 short plants. What is the most probable genotype distribution among these offspring?

Explanation

The presence of both tall and short plants in a 3:1 ratio suggests that the offspring include all three genotypes: homozygous dominant (TT), heterozygous (Tt), and homozygous recessive (tt). This indicates a typical Mendelian inheritance pattern for a single gene with dominant and recessive alleles.
