I believe the answer is minerals.
Minerals are inorganic substances that the body cannot manufacture but that act as catalysts, regulating many vital body processes. Nutrients are substances in food that the body needs to function properly to grow, repair, and supply it with energy. These includes, carbohydrates, proteins, lipids, vitamins and minerals.
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.
Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
