The correct answer is A.True
Yes, it is true that inheritance of character in offspring can only be possible if one of the parents will have that character. Genes play a major role in the inheritance of a character from parents to children. Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. These alleles contain traits, one or both of the above alleles could be expressed.
Gregor Mendel was the first person to describe the manner in which traits are passed on from one generation to another.
The man couldn’t have fathered the following child.
<u>Explanation:</u>
The blood grouping system in humans is called ABO blood grouping. The possible blood groups of humans are A,B,AB and O. ABO blood grouping is an example of co-dominance where both alleles of the ABO gene are expressed equally.
The ABO gene has 3 alleles. They are I^A,I^B and i. the alleles I^A,I^B are dominant over i. Person with the genotype I^A I^A and I^A i has the blood group A while a person having the genotype I^B I^B and I^B i has the blood group B. The person with the blood group will have the genotype I^A I^B.
Here the mother’s blood group is O which means her genotype is ii. The man’s blood group is AB which means his genotype is I^A I^B. The possible genotypes of the children are I^A i,I^A i,I^B i,I^B i with respective phenotypes A, A, B and B.
There is no possibility that the child can have the blood group O which means that the man could not have fathered the child.
