If white colour flower of Antirrhinum sp. successfully crossed with the pink
colour flower, what would be the proportion of white and pink color flowers
in the next generation?
- A 1:1
- B 3:2
- C 2:3
- D 2:1
Answer & Solution
Correct Answer
(A) 1:1
Step-by-step Solution
Detailed explanation
Parents: White (WW) \( \times \) Pink (RW) Gametes: W, R, W F1 generation: WW \( \times \) RW \( \implies \) 1/2 RW (Pink) : 1/2 WW (White) Proportion of white : pink = 1 : 1

- Read the given passage and answer the question.
ABO blood groups in human beings are controlled by the gene I. The plasma membrane of the red blood cells has sugar polymers that protrude from its surfaces and the kind of sugar is controlled by the gene. The gene (I) has three alleles IA, IB and I. The alleles IA and IB produce a slightly different form of the sugar while allele i does not produce any sugar. Because humans are diploid organisms, each person possesses any two of the three I gene alleles, IA and IB are completely dominant over I.

In the periodic table, the d-block contains the elements of group \(3\) to \(12\). The d-orbitals are progressively filled in each of the four long periods. The elements of d block referred as transition metals have partly filled d orbitals and exhibit certain characteristic properties such as variety of oxidation states, formation of coloured ions, act as catalyst and show paramagnetic behaviour.
The two inner transition metals series \(4f\) and \(5f\) are known as Lanthanoids and Actinoids respectively. The lanthanoids resemble one another more closely as compared to ordinary transition elements in any series.
