Genetic Inheritence

Question 1

Complete Dominance

Answer 1

1 dominant allele masks the recessive

Question 2

Codominance

Answer 2

2 codominant alleles can both be present and expressed (ABO blood types)

Question 3

Incomplete Dominance

Answer 3

heterozygote is a mix of the alleles (gradient of phenotypes)

Question 4

Penetrance

Answer 4

% of individuals with a given phenotype who display the associate phenotype

Question 5

Expressivity

Answer 5

severity of a phenotype

Question 6

Autosomal Inheritance

Answer 6

no sex bias, trait inherited through autosomes

Question 7

Autosomal Dominant Inheritance

Answer 7

a person who inherits just 1 copy of dominant allele will express dominant phenotype

Question 8

Autosomal Recessive Inheritance

Answer 8

a person must inherit both recessive copies, can skip generations, marked by carriers

Question 9

X-Linked Recessive Inheritance

Answer 9

expressed in females who have the recessive allele present on both x chromosomes, expressed in males if they only have 1

Question 10

Law of Segregation

Answer 10

allele pairs segregate randomly from each other into gametes during meiosis

Question 11

Law of Independent Assortment

Answer 11

alleles from separate traits are independently inherited

Question 12

Law of Dominance

Answer 12

recessive alleles are masked
