Multople Alleles

Question 1

Multiple alleles

Answer 1

more than 2 alleles for the same gene

Question 2

When multiple alleles exist there will be a hierarchy of dominance

Answer 2

Ex: fruit flies have different eye colours:

Red, apricot, honey, white

Question 3

Dominant or codominant alleles are identified with a capital letter and or superscripts of letters

Recessive alleles are identified a lower case letter

Question 4

• Human blood is a multiple allele system
• There are 3 different alleles that make 6 genotypes and 4 phenotypes
• the alleles control the production of antigens on red blood cells

Question 5

Antigen

Answer 5

substance that causes your body to produce antibodies against it

Question 6

• Allele IA produces antigen A on the red blood cells
• Antigen IB produces antigen B on the red blood cells
• Antigen i produces no antigen

Question 7

Type A blood can receive from A and O blood

Question 8

Type B blood can recieve from type B and O blood

Question 9

Tyoe AB blood is a universal acceptor (A, B, AB, O)

Question 10

Type ii blood can only recieve from O blood(universal donor)

Question 11

Type A blood produces immune response to type B and type AB blood

Question 12

Type B blood produces immune response to type A and AB blood

Question 13

Type AB blood doesn’t form any antibodies since it’s a universal acceptor

Question 14

Type O blood forms antibodies against A and B blood

Question 15

Since type O blood doesn’t produce antigens they can donate to everyone else

Question 16

Type AB blood is an example of codominence as both antigens are present on the cell

Question 17

IAi blood and IBi blood are examples of dominant inheritance because A and B type blood are dominant to O type blood
