Obama family portrait, 2011. 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 ...
Sexual reproduction is a biological process that creates a new organism by combining the genetic material of two organisms in a process that starts with meiosis, a specialized type of cell division. Each of two parent organisms contributes half of the offspring's genetic makeup by creating haploid gametes. [8]
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.
An important aspect of the formation of the parent offspring is the chromosome, which is a structure of DNA which contains many genes. [ 1 ] To focus more on the offspring and how it results in the formation of the f1 generation, is an inheritance called sex linkage , [ 1 ] which is a gene located on the sex chromosome , and patterns of this ...

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.
DNA paternity testing is the use of DNA profiles to determine whether an individual is the biological parent of another individual. Paternity testing can be especially important when the rights and duties of the father are in issue and a child's paternity is in doubt. Tests can also determine the likelihood of someone being a biological ...
