Identify the wrong statement with reference to the gene ‘I’ that controls ABO blood groups.
- AThe gene (I) has three alleles.
- BA person will have only two of the three alleles.
- CWhen I
A
and I
B
are present together, they express same type of sugar. - DAllele ‘i’ does not produce any sugar.
Solution & Step-by-step Explanation
The ABO blood group is controlled by gene I, which has three alleles: I
A
, I
B
, and i.
I
A
and I
B
produce slightly different types of sugar.
When I
A
and I
B
are present together, they both express their own types of sugars because of codominance. They do not express the same type of sugar.
Allele i does not produce any sugar.
Since humans are diploid, an individual possesses only two alleles.
A
, I
B
, and i.
I
A
and I
B
produce slightly different types of sugar.
When I
A
and I
B
are present together, they both express their own types of sugars because of codominance. They do not express the same type of sugar.
Allele i does not produce any sugar.
Since humans are diploid, an individual possesses only two alleles.
