The large number of potential gene make it unlikely that any two people will be identical. urgen 1. mutattions 2. combonations 3. frequency

The correct answer is option 2, that is, combinations.

The production of offspring with combinations of traits, which vary from those found in either of the parents is known as genetic reshuffling or genetic recombination. The genetic recombination, in eukaryotes, can result in the generation of a new set of genetic information, which can be conducted on from the parents to the offspring. Due to these variations, it is unlikely that any two individuals will be similar.
