Organisms can be homozygous or heterozygous for a gene. Homozygous means that the organism has two copies of the same allele for a gene. An organism can be homozygous dominant, if it carries two copies of the same dominant allele, or homozygous recessive, if it carries two copies of the same recessive allele. Heterozygous 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). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous. People with CF are homozygous recessive. Since Huntington's disease is autosomal dominant, people with the disease can be either homozygous dominant or heterozygous. This means RW is hetrogenous Correct answer is C.
