hardy weinburg Flashcards
what is it used for?
mathematic model used to determine allele frequency
what is a gene pool?
= all the alleles of all genes in a population at one time
what is a population?
= all the individuals of one species in one area at one time
what is allle frequency?
proportion of alleles in a gene pool
what does it assume?
= that there is no change i allele frequency between generations in a population
What are the 3 main asssumptions?
= no mutatons to create new alelles
= large population
= no migraton o introduce or remove alleles from the opulation
what is the equation?
p^2 + 2pq + q^2 = 1
p= freuqnecy of dominant allele
q= frequecy of reccesibe allele
p^2= homozygous dominant geptype
q^2: frequency of homozyous recessibe genotype
2pq: eteroxyhpus hepyu[
What are possible errors?
= if the alleles do not add up to ome, they arent alleles of the same gene
= if they add upt o less than one, another ossible allele
=frquencyes ust be in decimaals
when should we use this princile?
= one gene
= 2 alleles
= one dominant and one reccessive
When not to use equation/?
= codominance
= as tere are 2 allels x aleles by 2
=
What do we do if it says that to not use hardy winburg?
= multiple entire population by 2, take the ones with the same amount and multiply by 2, and add them with the others, divide by the total.
