Question

There are five known haplotypes among American Indians. One, however, is baffling because it is found in the Middle East and Europe rather than Asia. This is:

A) Haplotype A
B) Haplotype B
C) Haplotype C
D) Haplotype D
E) Madame "X"

Answer 1

The baffling haplotype found among American Indians in the Middle East and Europe is Haplotype B. This is an example of multiple alleles, similar to the ABO blood-type system in humans.

Step-by-step explanation:

The baffling haplotype found in the Middle East and Europe rather than Asia among American Indians is Haplotype B. This is an example of multiple alleles, similar to the ABO blood-type system in humans.

In the ABO blood-type system, there are three alleles: IA, IB, and i. Both IA and IB are dominant over i, and IA and IB are codominant with each other. The IA allele codes for A molecules on red blood cells, the IB allele codes for B molecules, and the i allele codes for no molecules. When there are three alleles, there can be six different genotypes and various phenotypes.

Similarly, the baffling haplotype B found in the Middle East and Europe among American Indians suggests the presence of multiple alleles in the population, resulting in diverse genotypes and phenotypes.
