Question
A homozygous tall (TT) pea plant looks the same as a heterozygous tall (Tt) pea plant. How can these two plants, which have different genotypes, look the same? (minimum of 2 sentences, including the terms Dominant and Recessive)(4 points)

Answer 1

The homozygous tall pea plant (TT) and the heterozygous tall pea plant (Tt) both display the dominant phenotype of tallness because the allele for tallness (T) is dominant over the allele for shortness (t). As a result, both genotypes express the same physical characteristic, making it impossible to differentiate between them based solely on their appearance.
