Final answer:
SNPs, or single nucleotide polymorphisms, are genetic traits that involve variations in a single nucleotide between individuals.
Step-by-step explanation:
SNPs, which stands for single nucleotide polymorphisms, are genetic traits that involve variations in a single nucleotide between individuals.
These variations can be used to determine the degree of relatedness between individuals or to identify someone from a tissue sample. SNPs are often analyzed in genome-wide association studies (GWAS) to identify genetic differences that may be involved in causing diseases.
The identification of SNPs can also be used in personal genomics to assess an individual's risk levels for various diseases.
