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

Options:

Answer:
C
Solution:

Gregor Mendel, conducted hybridisation experiments on garden peas for 7 years (1856-1863) and proposed the laws of inheritance in living organisms. Mendel selected 14 true-breeding pea plant varieties, as pairs which were similar except for one character with contrasting traits. In a human population there are 3 alleles for ABO Blood group (IA, IBand i). In Drosophila, genes for white eye and yellow body show 1.3 % recombination
