Which term(s) best describes the inheritance of human blood types?
incomplete dominance and multiple alleles
codominance and epistasis
codominance and multiple alleles
incomplete dominance and codominance
A personal with type AB blood has which genotype?
type A
AA
IAIA
IAIB
There are multiple alleles for the ABO blood group. Why are only two of these alleles present in any one individual?
Each parent contributes only one allele for the ABO blood group to the offspring.
There are not enough nucleotides in a red blood cell to produce a third allele.
Each allele in the ABO group must be dominant or recessive
Blood group alleles are not segregated during meiosis.
What are the blood types of the possible children that a woman (type O) and man (type AB) can have?
O and AB
O and A
O and B
A and B
If the offsprings have the blood groups O and A the genotype of parents would be
IAIA and IAi
IA i and ii
IAIA and IAIA
IA i and IBi
