why would shuffling genetic material to produce new combinations of characteristics be advantageous to a species?
Radda [10]

Answer:

Suffling of genetic material increases genetic variation in offspring which is important for evolution.

Explanation:

Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.

In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.

Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.
