Solution

The correct option is B Segregation

A.Dominance – In a pair of contrasting characters, one character is expressed and another character is not expressed. The expressed character is called Dominant character and not expressed character is called recessive character. This is called Law of dominance. It is the first law of Mendel’s.

B.Segregation - During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene. Law of independent assortment. Genes for different traits can segregate independently during the formation of gametes. Due to this in the F2 generation, 3:1 ratio of tall and dwarf progeny are formed.

C.Hybridization - the process of interbreeding between individuals of different species or genetically divergent individuals from the same species.

D.Crossing over – exchange of genetic material between the non sister chromatids of a bivalent is called crossing over.

So, the correct option is ‘segregation’.
