O-group child cannot have parents of following blood groups.
O-group child cannot have parents of following blood groups.
Show Hint

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Blood group inheritance follows Mendelian genetics.
A child with blood group O can only inherit O alleles from both parents.
Parents with AB and O blood groups cannot have an O-group child because the AB parent has A and B alleles, no O allele.
Therefore, O-group child cannot have parents with blood groups AB and O.
A child with blood group O can only inherit O alleles from both parents.
Parents with AB and O blood groups cannot have an O-group child because the AB parent has A and B alleles, no O allele.
Therefore, O-group child cannot have parents with blood groups AB and O.

- Study the cross given below:
- Assertion (A): When the two genes in a dihybrid cross are situated on the same chromosome, the proportion of parental gene combinations is much higher than non-parental type.
Reason (R): Higher parental gene combinations can be attributed to crossing over between two genes.
