<span>The independent variable is the part of the experiment that the researcher makes changes or adjustments to. This allows for differences in the dependent variable, which is usually the result that the independent variable is considered to (in)directly work on.</span>
Some offsprings look like their parents because we all have different genes. Different combinations of genes for one of these traits create a bunch of different physical attributes. Even though we get all our DNA from our parents, each of us has a unique combination of genes.
Law of segregation states that <span>gametes carry one allele for each trait
As it states that
</span>that during the production of gametes the two copies of each hereditary factor segregate<span> during the production of gametes</span> so that offspring acquire one of the two allele from each parent
so option C is correct
hope it helps
I believe the answer is a. crossing over
