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
