What will happen if both the characters present in `F_(1)` generation pass together in `F_(2)` generation?

Text Solution

Verified by Experts

If both the characters present in `F_(1)` generation pass together in `F_(2)` generation, then gametes and offsprings would receive double dose of information, that will be abnormal.

What is the difference between F_(1) generation and F_(2) generation?

What is alternation of generation ?

In a cross between plants with purple flowers and plants with white flowers the offsprings of F_(1) generation all had white flowers. When the F_(1) generation was self-crossed, it was observed in the F_(2) generation that out of 100, 75 flowers were white. Make a cross and answer the following : (i) What are the genotypes of the F_(2) progeny? (ii) What is the ratio of 'White : Purple' flowers in the F_(2) generation?

With the help of one example each provide genetic explanation for the following observations: brgt (i) F_1 -generation resembles both the parents. F_1 -generation does not resemble either of the parents

In a monohybrid cross between tall pea plants (TT) and short pea plants (tt) a scientist obtained only tall pea plants (Tt) in the F_(1) generation. However, on selfing the F_(1) generation pea plants, he obtained both tall and short plants in F_(2) 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.

In Mendel's monohybrid cross between tall and short pea plants, all offsprings were tall. What does this tell us about the trait? What is the ratio of tall and short plants in the F_(2) generation?

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, F_(1) only tall plants appeared. (i) What happens to the traits of the dwarf plants in this case? (ii) When the F_(1) generation plants were self-fertilised, he observed that in the plants of second generation, F_(2) both tall plants and dwarf plants were present. Why it happened? Explain briefly.
