Four,six

Vedclass · Answer

(B) The correct answer is $B$ (Four,six).$ABO$ blood groups in humans are controlled by the gene $I$. The gene $I$ has three alleles: $I^{A}$,$I^{B}$,and $i$.$1.$ The alleles $I^{A}$ and $I^{B}$ produce slightly different forms of sugar,while the allele $i$ does not produce any sugar.$2.$ Because humans are diploid,each individual possesses any two of these three alleles. This results in the following six possible genotypes: $I^{A}I^{A}$,$I^{A}i$,$I^{B}I^{B}$,$I^{B}i$,$I^{A}I^{B}$,and $ii$.$3.$ Due to the dominance relationships ($I^{A}$ and $I^{B}$ are dominant over $i$,and $I^{A}$ and $I^{B}$ are codominant with each other),these six genotypes result in four distinct phenotypes: $A$,$B$,$AB$,and $O$.Genotype of OffspringBlood Type of Offspring$I^{A}I^{A}$$A$$I^{A}i$$A$$I^{B}I^{B}$$B$$I^{B}i$$B$$I^{A}I^{B}$$AB$$ii$$O$
