Your lab specializes in assessing genetic variation between human populations in european countries. What type (s) of analysis would you most likely perform

The answer is single nucleotide polymorphisms (SNPs)

It checks for variation in nucleotide sequences in particular genes that may be different among people, especially in different races. An example is a gene for melanin that would determine the trait for skin color. Single nucleotide changes in the gene between population can be used to differentiate populations.
