Genee are: segments of DNA inherited by the offspring from the parent Considered responsible for the development of behavioural characteristics.

• True

• False

Genotype is

• the set of characteristics a person actually develops

• The genetic makeup of an individual

Phenotype

• the set of characteristics a person actually develops

• The genetic makeup of an individual

Concordance rate

• the measure of degree of similarity (twin studies)

• the difference between a set of genes in family studies

Inheritance is when genes and their DNA are passed down from parents to their offspring

• false

• true

Monozygotic

• formed from two separate fertilized eggs, and have about 50 % of their genes in common

• genetically identical because they are formed from one fertilized egg that splits into two

Dizygotic

• formed from two separate fertilized eggs, and have about 50 % of their genes in common

• genetically identical because theu are formed from one fertilized egg that splits into two

Behavioural Genetics

• understanding of how genetics and environment contribute to individual variations in human behaviour, where the premise is that the inheritance of DNA influences behaviour.

• understanding of how genetics influences behaviour

Adoption studies

• Study behaviour between family members who have similar genetics to different degrees. Inheritance

• Allow researchers to study the comparison between genetic and environmental influence on behaviour.
