|Frequency of alleles
||The abundance of a particular allele in relation to the sum
of all alleles at that locus in a population is called
frequency of an allele.
||The total genes of a trait in a population are called gene pool.
||The combination of the principles of population genetics
and Darwinianevolutionary theory is called modern
The study of the genetic events in gene pools is called population genetics.
||The change in gene frequencies by chance is caileo
||Changes in gene frequency due to migration of individuals are called gene flow
||The measure of the tendency for gene frequencies tc change through mutation is called mutation pressure.
||The tendency for natural selection to occur and upset
Hardy-Weinberg equilibrium is called selection pressure
||The selection in which individuals at one phenotypic
extreme are at a disadvantage as compared to all other individuals in the population is called directional selection
||The natural selection in which individuals of the most
commons phenotypes are at disadvantage is called

||The occiiirence of ‘two or more distinct forms in a

|Balanced polymorphism occurs when different
phenotypes are maintained • at relatively stable
frequencies in the population. ,
||Then condition in which heterozygote is more fit than either homozygote is called heterozygote superiority.
||The speciation occurs in demes is called parapatric
||Deme is a small and local population
||The speciationoccurs in small local population called
demes is called parapatric speciation.
