M5: population genetics and single nucleotide polymorphins Flashcards
(7 cards)
gene pool?
sum of all genes and their alleles within a population
genetic diversity?
total of all genetic characteristics in a genetic makeup
genetic variation?
tendency of an individual’s genetic traits in a population to vary
allele frequency?
The measure of how common an allele is within a population. calculated by counting the number of copies of an allele in a population and dividing by the total number of copies of all alleles in the gene
polymorphism?
when indivuals have different phenotyoe as a result of mutation giving rise to different alleles
SNP?
Single-nucleotide polymorphism
typing error in DNA where a nucleotide is replaced by another
Why are SNPS important?
scientists use them as genetic markers to study evolution patterns and locate genes that are linked to specific diseases
