Question

how do variations occur in an offspring​

Answer 1

Variation occurs in an offspring by the variation in the genes. Such as, father contains one kind of gene and mother contains another kind of genes. And when they come in caution then there is the fusion of both the genes and the newly born offspring carries those genes but not identically same of any of the parents but some characteristics from both the parents. So, we are getting variation in the genetic material and the same thing again happens when the offspring involves in the process of reproduction and it continues from generation to generation. So, there is the variation in the newly born offspring.

Answer 2

Explanation:

Variation::::

♥ variation represents the visible differences shown by the individuals within the offspring and species

♥ Responsible for the diversity within the population

♥ leads to evolution by introducing new phenotypic characters to the species

♥ eye colour , skin colour , dimples are examples

Reasons:::

♥ Genetic variability of offspring ::

Sexual reproduction , independent assortment

♥ Mutation

♥ Recombination of genes
