What must happen to the genetic material from each parent before sexual reproduction can occur?

The chromosomes from each parent sex cell must interact with each other in a process called crossing over. Crossing over allows the exchange of genes between the two chromosomes.

Change in genetic material of an organism from one genrartion to another?
When mutations happen, they cause the alteration of genetic material.
Why is there great variations in the offspring produced through sexual reproduction but little or no variations in the offspring produced through asexual reproduction?
In asexual reproduction there is no independent orientation of chromosomes, not crossing over and no random fertilization. Cloning the exact genetic material from organism to progeny is all asexual reproduction is. So, very little chance of anything but mutation, copying errors, are going to happen in asexual reproduction.
What would happen if the nucleus didn't have genetic materials?
A cell cannot function without genetic material (with the exception of red blood cells, which do function without genetic material - all they have to do is to contain hemoglobin and float in the blood as it circulates). However, in organisms called prokaryotes the genetic information is not present in the nucleus but in the cytoplasm. This is possible because their genetic material is very simple and does not need the nucleus to protect it from harm.
What will happen to a cell if the nucleus is absent?
Cell division would not take place and genetic material would not pass on to the next generation.
Does meiosis result in genetic variation?
Mitosis produces two daughter cells that are genetically identical to the original parent cell. Therefore there is no variation (except when things like mutations happen). Meiosis produces haploid daughter cells - this means that they only contain half the number of chromosomes (or genetic material) as the original parent cell. These cells then go on to participate in sexual reproduction and fuse with a different haploid cell. Therefore the resulting organism recieves half the genetic material from each - and is identical to neither.

What is copied before mitosis begins?
DNA, the genetic material, of course. Also mitochondria and chloroplasts need to divide. This is the process of mitosis where two daughter cells are produced and both will need the complete complement of genetic material; DNA.

How do the complementary base pairing requirements ensure DNA's ability to act as the genetic material?
The DNA acts as the genetic material because it acts as a code. The requirements for the complimentary base pairings ensures information doesn't accidentally change during the incredible number of cell divisions that happen each day.
