Question

Why did the f1 offspring of mendel's classic pea plant crosses always look like one of the two parental varieties?

Answer 1

The F1 offspring of Mendel's classic pea plant crosses always looked like one of the two parental varieties because he crossed a homozygous dominant plant with a homozygous recessive plant so each plant received one recessive allele and one dominant allele. All of the plants looked like one plant because the dominant allele overshadowed the recessive allele
