how do melosis and sexual reproduction (fertilization) produce offfspring that differ from the parents?
 
What happens is that the sex cells or gametes fuse and mix their chromosomes. In humans, both the egg and the sperm have 23 chromosomes instead of the usual 46. Therefore, when they join they combine to create a single cell with the normal 46 chromosomes - but half of these are traits or characteristics of the father and half are of the mother.

This is why you can have eyes like your dad but have your mother's hair colour - you may have the chromosome that controls eye colour from your dad's sperm cell but the chromosome that controls hair colour from your mothers egg.
