The following blanks can be filled only by numbers.
1. Gregor Mendel conducted hybridization experiments on garden peas for (P) years.
2. Mendel selected (Q) true-breeding pea plant varieties
3. In a human population, there are (R) alleles for ABO blood group.
4. In Drosophila, genes for white eye and yellow body show (S)% recombination.
The correct arrangement is
Gregor Mendel, conducted hybridisation experiments on garden peas for P- seven years (1856-1863).
Mendel selected Q- 14 true-breeding pea plant varieties, as pairs which were similar except for one character with contrasting traits.
In a human population, there are R-three alleles for ABO blood group.
In Drosophila, genes for white eye and yellow body show only S-1.3 per cent recombination.
Therefore, S< R< P< Q
