Whats a genetic basis of behaviour

Answer 2

The study of whether behavioural characteristics ( intelligence, personality, mental disorders) are inherited like phenotypes ( aka eye colour) are.

Question 3

Studies used to show genetic basis of behaviour

Answer 3

Twin studies used to determine likelihood traits have a genetic basis.
-done by comparing concordance between twins ( rate of which they share same characteristic )
MZ = higher concordance rate
DZ = less high

Question 4

identical twins

Answer 4

(MZ) Monozygotic twins, share 100% of genes.

Question 5

non identical twins

Answer 5

Non-identical twins = (DZ) Dizygotic twins, share 50% of their genes.

Answer 7

product of what happens when genotype and environment interact.
