i'm not sure what law of segregation is cuz i think i learnt it under a different name.

but anyways in a nut-shell, both of them are just to assist in creating more variations within a speices.

Independent Assortment is just to describe the chromosomes lining up in different alignments so that different arrangements of chromotids move into the gamete and the Law of Segregation is just to describe the chromosomes spittling into two different daughter cells.

with both of them combined, they increase variablilty in offspring. and you have to also consider fertilisation as a random process, and crossing over as a form of introducing more variables into daughter cells.
