WebHeterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white).

WebHomozygotes ( L^ML^M LM LM and L^NL^N LN LN) have only M or an N markers, respectively, on the surface of their red blood cells. However, heterozygotes ( L^ML^N LM LN) have both types of markers in equal numbers on the cell surface.
