In pea plants, tall (t) plants are dominant over short (t) plants. if a heterozygous (tt) pea plant is crossed with a homozygous dominant (tt) pea plant, all of the resulting pea plants should be tall (tt or tt). each plant will receive a dominant allele from the homozygous dominant plant, while they could receive either a dominant or recessive allele from the heterozygous plant. the fact that each plant gets only one allele from each parent plant is detailed in the law of a. genetic inheritance b. multiple alleles c. independent assortment d. segregation
