A person's biological parents are the persons from whom the individual inherits their genes.The term is generally only used if there is a need to distinguish an individual's parents from their biological parents, For example, an individual whose father has remarried may call the father's new wife their stepmother and continue to refer to their mother normally ...
All of the definitions were written by the same Ph.D.-level science writer for consistency and accuracy. Illustrations: Most terms have professionally drawn illustrations to further explain a meaning or concept, or place them in context of the cell or a similar biological setting as a means to better explain the term.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The improved or increased function or quality of any biological trait in a hybrid offspring, with respect to the same trait in its genetically distinct parents. If any one or more of the parents' traits are noticeably enhanced in the offspring as a result of the mixing of the parents' genetic contributions, the offspring is said to be heterotic.

Genes are inherited as units, with two parents dividing out copies of their genes to their offspring. Humans have two copies of each of their genes, but each egg or sperm cell only gets one of those copies for each gene. An egg and sperm join to form a zygote with a complete set of genes. The resulting offspring has the same number of genes as ...
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
A genetic lineage includes all descendants of a given genetic sequence, typically following a new mutation.It is not the same as an allele because it excludes cases where different mutations give rise to the same allele, and includes descendants that differ from the ancestor by one or more mutations.
