What is that A-A genotype ?,usually A pairs with G nucleotide..Can any one explain that

A-A genotype doesn't mean bond between two adenosine nucleotides. It means that two adenosine nucleotides in the single DNA chain are placed next to each other. Same is with G-G genotype. They form complementary bonds with their usual nucleotide pairs (A-T, and G-C) in other chain.

Then how it was proved that Individuals with A-A genotype dead in morning and G-G in evening?

Simply, by calculating (statistically) the number of people having one or another type of genotypes and the time of death - they concluded that people with A-A genotype have more chance to die in the morning, and G-G in the evening.
