epigenetics

Question 1

induction

Answer 1

where a genes expression is increased

Question 2

expressivity

Answer 2

degree a trait is expressed
dark brown hair has a higher expressivity than light

Question 3

allele

Answer 3

two genes at the same location that influence a specific trait
blue eye color and brown eye color

Question 4

single gene trait

Answer 4

two copies of a gene that has two distinct phenotypes
cleft chin vs no cleft chin

Question 5

polygenetic trait

Answer 5

involves multiple genes at a different location that all come together to determine a trait
bell curve
height

Question 6

multifactorial inheritance

Answer 6

many genes affect outcome as well as environment
