Question

during meiosis some of the genes inherited from your mother get swapped onto the strand of DNA you inherited from your father and vice versa. the event is called crossing over. what is the ultimate result of crossing over

Answer 1

Genetic Variation (having different traits from your mom and dad)

Answer 2

The main result of crossing over is the genetic recombination.

In prophase of the first division of meiosis, paired homologous chromosomes exchange portions of chromatids by performing chiasmas: recombinant chromosomes are obtained.

This phenomenon is the crossing-over that causes intrachromosomal mixing between alleles of homologous pairs.
