Topic 53

Question 1

Methods of parentage control

Answer 1

blood groups and DNA allele polymorphisms

Question 2

Polymorphism

Answer 2

two or more phenotypes existing in the same population

Question 3

Why is polymorphism important for parentage control?

Answer 3

Because of selective mating and estimation of relationship

Question 4

level of differences - phenotype

Answer 4

not always visible; morphological; serological: blood groups, HA; biochemical: proteins and enzyme polymorphisms

Question 5

Parentage control with blood groups

Answer 5

used in wide range; cheap, fast, accurate; blood group antigen; simple codominant inheritance; 90% certainty

Question 6

Blood group antigen

Answer 6

generally determined antigen set on surface of RBC inherited from parents. All animals inherit antigen only from parents

Question 7

DNA polymorphisms

Answer 7

there are two or more alleles in the population with notable frequencies

Question 8

DNA polymorphism examination strategies

Answer 8

RFLP, PCR

Question 9

RFLP

Answer 9

Restriction fraction length polymorphisms

Question 10

PCR

Answer 10

Polymerase chain reaction used to compare offspring to parent DNA
