Which of the following phenomena leads to variation in DNA
a)Linkage, mutation
b)Recombination, Linkage
c)Mutation, Recombination
d)Aneuploidy, Linkage

Dear student, 
​Please find below the solution to the asked query                

Recombination and mutation are two phenomena which lead to variation in DNA.

DNA mutations are the sudden changes that takes place in the DNA sequence of an organism. These are the permanent changes that can be either induced or occur naturally leading to the variation in the populations. 

DNA recombination is the process which involves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome. It leads to the formation of new combinations. The consequence of these kind of new combination are new characters and traits in the organism.

Hence, option (c) is correct.
