Principle Of Inheritance And Variation Question 373
Question: Which of the following parental phenotypes would produce offspring with blood group phenotypes in the expected ratio of 1 type A: 1 type B?
Options:
A) Blood group of mother Blood group of father A B
B) AB AB
C) AB B
D) AB O
Show Answer
Answer:
Correct Answer: D
Solution:
[d] The mother would have genotype $ I^{A}I^{B} $ and the father would have genotype $ I^{O}I^{O} $ Thus, the two genotypes possible for their offspring would be $ I^{A}I^{O} $ and $ I^{B}I^{O} $ with equal probability.
Hence, the expected phenotypes would be 1 type A: 1 type B.
