Consider the following statements regarding ABO blood group in human. I. It is controlled by multiple alleles. II. It shows codominance III. Presence of fats on the surface of the RBC Which of the following statement(s) given above are false ?
1 Only I
2 I and II
3 II and III
4 III
Explanation:
The plasma membrane of the red blood cells has sugar polymers that protrude from its surface and the kind of sugar is controlled by the gene.

Multiple alleles are present:
1 On different chromosomes
2 On non-sister chromatids
3 At the same locus on the chromosome
4 At different loci on the same chromosome
Explanation:
Multiple alleles are present at the same locus of chromosome. Though only two of the alleles can be present in a single organism. Multiple alleles is a condition where a gene exist in more than two allelic forms which are present on the same locus of the chromosome. For example - ABO system in humans.

Which one of the following statements is wrong?
1 There are six different genotypes of the human \(\mathrm{ABO}\) blood types.
2 \(\mathrm{ABO}\) blood grouping provides a good example of multiple alleles.
3 Mendelian disorders cannot be traced in a family by the pedigree analysis.
4 The genetic make-up of the sperm determines the sex of the child.
Explanation:
Mendelian disorders are the disorders that are caused by mutation or alteration in single genes. These disorders can be traced in a family with the help of pedigree analysis but cannot be confirmed by using karyotyping.

A mother with blood group B type has a child with blood type O. What is the possibility of the genotypes of that mother and father?
1 \({I^A}{I^B}\) (father) and \({I^B}{I^B}\) (mother)
2 \({I^A}{I^A}\) (father) and \({I^B}{I^O}\) (mother)
3 \({I^B}{I^o}\) (father) and \({I^A}{I^O}\) (mother)
4 \({I^A}{I^O}\)(father) and \({I^B}{I^O}\) (mother)
Explanation:
Both the parents are heterozygous to the trait, and the child has received recessive traits from either parent.
