The Hardy-Weinberg Law: The Hardy-Weinberg law rests on these assumptions: • The population under study is large, and matings are random with respect to the locus in question. • Allele frequencies remain constant over time because of the following: • There is no appreciable rate of new mutation. • Individuals with all genotypes are equally capable of mating and passing on their genes; that is, there is no selection against any particular genotype. • There has been no significant immigration of individuals from a population with allele frequencies very different from the endogenous population. A population that reasonably appears to meet these assumptions is considered to be in Hardy-Weinberg equilibrium. Problem: A rare disease which is due to a recessive allele (a) that is lethal when homozygous, occurs within a specific population at a frequency of one in a million. How many individuals in a town with a population of 14,000 can be expected to carry this allele? #NikolaysGeneticsLessons #Genetics #ABOBloodGroup #populationGenetics #alleleFrequency #Genotype #Phenotype #hardyWeinbergAssumptions #hardyWeinberg #alleleFrequencies #genotypeFrequencies #hardyWeinbergEquations #hardyWeinbergEquilibriumExplained #hardyWeinbergPrinciple #Alleles #Dominant #recessive #assumptions #educational #science #biology #cartoon #animation #tutorial #introduction #explanation #HardyWeinberg #probabilityInGenetics #ABOGroup #bloodType
