Genetic variation in a population arises due to:

Step-by-step solution

Genetic variation in a population Arise due to reshuffling of genes caused by recombination and mutations. Recombination occurs due to formation of synapsis during crossing over in cell division, while mutation are sudden heritable changes in the sequence of genome. Reproductive isolation and selection do not cause variation, as due to this, selective genome cause inheritance of similar traits in offspring.
