Crossing over adds even more variation to this. The three sources of genetic variability in a sexually reproducing organism are: Independent assortment of homologous chromosomes during meiosis I and of nonidentical sister chromatids during meiosis II. Crossing over between homologous chromosomes during prophase I.

Answered by smartbrainz

genetic variability arises during meiosis and fertilization and helps in certain small differences between the offspring and the parents.

Explanation:

during meiosis there is crossing over between the homologous chromosome. As a result of this there is genetic transfer between the chromosome.

During fertilization there is actually a single pair of allele which are responsible for the character and is is received from either parents. In addition to this fertilization also helps in finding the characteristics and independent assortment of them.
