Ch. 3 Nature & Nurture 3.

Question 1

Heritability

Answer 1

Statistical likelihood that variations observed in a population are because of genetics

Question 2

Genetic drift

Answer 2

Biological change from one generation to the next because of chance or accident

Question 3

Sexual selection

Answer 3

Development of traits that help an individual compete for mates

Question 4

Evolution

Answer 4

Descent with modification from a common ancestor

Question 5

Gene expression

Answer 5

Process where genetic instructions are converted into a feature of a living cell

Question 6

Phenotype

Answer 6

Observable characteristic

Question 7

Concordance rate

Answer 7

Statistical probability that a trait in one person will be shared by another

Question 8

Relatedness

Answer 8

Probability that two people share the same allele from a common ancestor

Question 9

Candidate gene

Answer 9

Has a greater impact on a trait of interest

Question 10

Recessive

Answer 10

Feature of an allele that produces a phenotype only in the homozygous condition

Question 11

Gene

Answer 11

Small segment of DNA located in a particular place on a chromosome and produces a protein

Question 12

Genome wide association study (GWAS)

Answer 12

Performed to look for variations associated with a particular phenotype, condition, or disease

Question 13

Allele

Answer 13

One of several versions of a gene

Question 14

Genotype

Answer 14

An individual’s profile of alleles

Question 15

Nurture

Answer 15

Contributions of environmental factors and experience to our physical structure and behaviours

Question 16

Heterozygous

Answer 16

Having two different alleles for a gene

Question 17

Homozygous

Answer 17

Having two of the Amie alleles for a gene

Question 18

Reciprocal altruism

Answer 18

Help you provide for another when you expect the favor to be returned

Question 19

Altruism

Answer 19

Behaviour on behalf of another that fails to benefit or harms the individual performing it

Question 20

Dominant

Answer 20

Feature of an Allele that determines a phenotype in either the homozygous or the heterozygous condition

Question 21

Nature

Answer 21

Contributions of heredity to our physical structure and behaviours

Question 22

Behavioural genetics

Answer 22

Scientific field that attempts to identify and understand links between genetics and an organisms actions

Question 23

Epigenetics

Answer 23

Study of gene/environment interactions in the production of phenotypes

Question 24

Natural selection

Answer 24

Process by which survival pressures act to change the frequency of alleles in subsequent generations

Question 25

Adaptation

Answer 25

Change because of natural selection

Question 26

Fitness

Answer 26

Ability of one genotype to reproduce more successfully relative to other genotypes

Question 27

Mutation

Answer 27

Error that occurs when DNA is replicated

Question 28

Migration

Answer 28

Movement to a new location
