Genetics, Natural Selection and Evalution - Blood Typing and Blood Genetics Flashcards
The human ABO gene is on chromosome __.
9
There are three versions (called “alleles”) of this blood type gene: __, __, and __.
A, B, O
The A, B, and O allele
combination a person has is their ____________.
genotype
Their blood type is their ___________.
phenotype
The “__” allele is dominant and so is the “__”
allele.
A, B
Together though, the “A” and “B” alleles are
_______________.
co-dominant
The “__” allele is recessive.
O
IAIA is Type __
A
_____ is Type AB
IAIB
_____ results in Type B
IBIB
ii is Type __
O
What are antigens?
An antigen is a protein (encoded from the right enzyme) that “sits” on the surface of your Red Blood Cells.
There are 2 different blood antigens, __ and __.
A,B
If you have the __ antigen, you have type A blood.
A
If you have the B antigen, you have type __ blood.
B
If a person has a positive __________, this means that their blood contains a protein that is also found in Rhesus monkeys.
Rh factor
Rh is expressed as either _________ or
__________.
Positive, negative
The Rh factor, like other antigens, is found on the __________ of the red blood cells.
