What is a heterozygous snip?

Answer 1

A heterozygous SNP (single nucleotide polymorphism) refers to a variation at a specific position in the DNA sequence where two different alleles are present in an individual. For example, one allele may have a nucleotide A, while the other may have a nucleotide G at the same locus. This genetic variation can influence traits, disease susceptibility, and responses to medications. Heterozygous SNPs are important in genetic studies as they contribute to genetic diversity within populations.
