genotypes

types of genotypes:

1. dominant - 2 copies of dominant allees

3. 2 recessive alleles

1. homozygous (PP)

2. heterozygous (Pp)

3. homozygous (pp)

An organism’s physical appearance or behavior

phenotype

we can have the same phenotypes but different __

genotypes

used to map out different genetic options based off parents

punnet square

most genes have more than alleles but we only inherit _

2

__ determine blood type

antigens

lack of A or B glycoproteins is what type of blood type 

type O 

1. __ are the dominant alleles

2. __ are the recessive alleles

A and B

O

__ fight the blood type not belong to you

antibodies

type A antigens have type __ antibodies

B

O blood type means no __

antigens (it’s bald)

when blood clumps together as a result of wrong blood transfusion
