Parent–offspring conflict (POC) is an expression coined in 1974 by Robert Trivers. It is used to describe the evolutionary conflict arising from differences in optimal parental investment (PI) in an offspring from the standpoint of the parent and the offspring. PI is any investment by the parent in an individual offspring that decreases the ...
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.
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 ...
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 ...
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 ...
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.
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]
A biological mother is the female genetic contributor to the creation of the infant, through sexual intercourse or egg donation. A biological mother may have legal obligations to a child not raised by her, such as an obligation of monetary support. An adoptive mother is a female who has become the child's parent through the legal process of ...
