Genes closer travel together
If someone starts ripping dictionaries apart at random places and handing you the pieces, you can bet that the chunk that contains meiosis will be more likely to contain mitosis than chromosome.

Sexual vs asexual: gain good genes & shed bad ones
Its descendants are no longer doomed to inherit a particular combination of alleles on each chromosome. Meiois shuffles the alleles into new combinations. Some of the fly’s descendants may inherit the alleles for frail wings and a weak immune system. But meiosis also allows other descendants to end up with powerful wings and a strong immune system. These stronger flies can reproduce, and their offspring will sustain the population into future generations. The population of flies ends up with combinations of superior genetic variants, while many harmful mutations disappear into oblivion.
