Question

Within the species of dogs, we can see pups looking very different from each other. This is because of ...................


  1. Sexual reproduction

  2. Genetic variation

  3. Both A and B

  4. Growth differences.


Solution

The correct option is C

Both A and B


Animals which we see around us with differences in them are the result of genetic variation. Sexual reproduction involves fusion of haploid gametes which in turn is the source of genetic variations at DNA level. These variations produce morphological differences in the animals of the same species.
