The answer to the question is Heterozygotes.
Genes that carry contrasting inheritance factors are called heterozygotes. In heterozygous individuals, the two genes for a trait, one received from the mother and the other from the father, are different. They have different forms of a particular gene. For example; pea plants can have red flowers and either be homozygous dominant (RR), or heterozygous (Rr).
