Genetic Concepts

Homozygous individuals are called pure.

Inheritance of characteristics determined by genes found on sex chromosomes (X or Y) is called sex- linked inheritance.

Chromosomes can be classified as autosomal or sex-linked.

Molecular phenomena may be related to the production of proteins by a gene or the interaction between two alleles of the same locus.

The sequence of nucleotides

Heterozygotes are known as hybrids.

DNA molecules are composed of a double-strand that has a helix shape

adenine (A), thymine (T), guanine (G), and cytosine (C).
