Question

question 40
there are 3 alleles that lead to the abo blood types. how many alleles does any one individual carry?
o 1
o 4
o 3
o 2

Explanation:

Step1: Recall the concept of alleles in ABO blood type

In the ABO blood type system, each individual has two alleles for the blood - type gene. One allele is inherited from the mother and the other from the father.

Step2: Analyze the number of alleles per individual

Since there are three alleles ( \(I^{A}\), \(I^{B}\), \(i\) ) in the population for the ABO blood - type, but an individual can only carry two alleles (one from each parent).
