प्रश्न
A man having blood group O marries a woman having blood group B and they have a daughter. What will be the blood group of the daughter?
उत्तर
The answer to this question depends on whether the blood group B of the woman has gene combinationIBIB or IBIO.
In the first case (i.e., when the blood group B has genotype IBIB), the daughter will have blood group B. This is because here the gene IB is dominant over gene IO.
In the second case (i.e., when the blood group B has genotype IBIO), there stands an equal chance for the genotype of the daughter's blood to be either IBIO or IOIO. Due to this, there is an equal chance for the daughter to acquire blood group B or blood group O.

In one of his experiments with pea plants, Mendel observed that when a pure tall pea plant is crossed with a pure dwarf pea plant in the first generation, F1, only tall plants appear.
(a) What happens to the traits of the dwarf plants in this case?
(b) When the F1-generation plants were self-fertilised, he observed that in the plants of the second generation, F2, both tall plants and dwarf plants were present. Why it happened? Explain briefly.
In a monohybrid cross between tall pea plants (TT) and short pea plants (tt), a scientist obtained only tall pea plants (Tt) in the F1 generation. However, on selfing the F1 generation pea plants, he obtained both tall and short plants in F2 generation. On the basis of above observations with other angiosperms also, can the scientist arrive at a law? If yes, explain the law. If not, give justification for your answer.
A cross was made between pure breeding pea plants one with round and green seeds and the other with wrinkled and yellow seeds.
(a) Write the phenotype of F1 progeny. Give reason for your answer.
(b) Write the different types of F2 progeny obtained along with their ration when F1 progeny was selfed.
