Evolution, Genes, Environment & Behaviour

Question 1

Darwin’s principle that traits enhancing survival and reproduction are preserved is known as:

Answer 1

Natural selection

Question 2

The specific genetic makeup of an individual is called the:

Answer 2

Genotype

Question 3

If a disorder results from interactions among many genes, it is termed:

Answer 3

Polygenic

Question 4

Chickens carry genes for teeth but lack them, illustrating the difference between:

Answer 4

Genotype and phenotype

Question 5

Adoption studies compare adoptees with their:

Answer 5

Biological siblings

Question 6

A disorder present only when two recessive alleles combine illustrates a(n):

Answer 6

Recessive trait

Question 7

Heritability estimates tell us about genetic influence on:

Answer 7

Population variance

Question 8

Gene–environment correlation where parents’ genes shape the environment they provide is called:

Answer 8

Passive

Question 9

Monozygotic twins are called so because they:

Answer 9

Develop from one zygote

Question 10

Epigenetic mechanisms primarily involve:

Answer 10

Methylation and histone modification

methylation and histone modifications are both crucial epigenetic mechanisms that regulate gene expression and influence cellular processes like development, differentiation, and aging

Question 11

A high heritability coefficient (> .7) implies:

Answer 11

Strong genetic contribution

Question 12

Strategic pluralism explains the maintenance of:

Answer 12

Multiple adaptive strategies
