Question

The term "Single Nucleotide Polymorphism" is a genetics term that indicates that at a locus there are multiple alleles that differ just by one single nucleotide base and each allele has a frequency of above 1% in a population.

a. True
b. False

Answer 1

True, a 'Single Nucleotide Polymorphism' (SNP) is a genetic variation where alleles differ by a single nucleotide and each allele is present at a frequency of over 1% in the population.

Step-by-step explanation:

The term "Single Nucleotide Polymorphism" (SNP) is indeed a genetic term that signifies a variation between individuals due to a change in a single nucleotide in their DNA sequences. This variation occurs at a specific locus when alleles differ by just one nucleotide base. Moreover, each allele must be present at a frequency above 1% in the population for it to be classified as an SNP. This definition correctly aligns with the concept that SNPs represent a common type of genetic variation among people and contribute to individual differences, which can affect how different individuals respond to drugs, vaccines, and other therapies.
