Hardy-Weinberg (W2-L1) Flashcards
Locus
Individual region on a chromosome
Alleles
Form of gene variance at a specific locus
Phenotype
Any observable and measurable characteristic of an organism
originates from wither genetic variation or environmental variation
Polygenetic
Multiple genes impact the phenotype
William Castle
Showed that genotype frequencies will remain stable in a population if there is no selection
G.H. Hardy
Mathematician that was a friend of Punnet who created the Hardy-Weinberg equation
Assumptions of the Hardy-Weinberg equilibrium
- Diploid, sexual organisms
- random mating
- NO mutation
- No gene flow
- No genetic drift
- No selection
P
Frequency of Dominant allele
of A allele /total gamates
q
Frequency of recessive allele
of a allele / total gametes
P^2
Genotype Frequency of AA (%)
2pq
Genotype Frequency of Aa (%)
q^2
Genotype Frequency of aa (%)
Allele Frequency
relative abundance of each allele expressed as a decimal proportion
Cryptic Species
individuals appear morphologically the same species , but are really separate populations
