HW equilibrium Flashcards
term that integrates natural selection with Mendelian genetics
population genetics
population genetic allows us to understand
changes in allele frequencies across generations
Augustinian monk from Czech republic that loved to garden, and cross fertilized true breeding plants
gregor mendel
mendelt determined that phenotypic variation was
heritable
definition- two alleles separate end up in different gametes one from each parent is passed to each offspring
principle of segregation
alleles of different genes ___ _____ from one another during formation of gametes
assort independently
punnet squares are used to predict
potential genotypes
allele frequency of gene pool yields a proportion of the population that should have particular
genotype
Punnett proposed that in an ideal population allele frequencies will remain
unchanged
Hardy Weinberg Equillibirum equation
p^2 +2pq+q^2 =1
5 assumptions of HW equilllibirum
- no selection
- no mutation
- no gene flow
- no random chance
5.individuals random mating
under HW contdition, all individuals survive and reproduce at
equal rates
under HW conditions, no new ____ were generated
alleles
Under HW conditions no individuals ______ in or out of population
move
under HW conditions, the populations is infinitely
large
under HW condtions, every individual in a population has an equal chance of ——– with every individual
reproducing
hw is useful because it rests upon a specific set of assumptions which when violated result in a change in
allele frequencies
HW does not hold it there is (5)
selection
mutation
migration
drift
nonrandom mating
the assumptions of hardy Weinberg provide a ____ ____ for investigating the causes of evolution
null model
