Industrial melanism is an example of:
Geographic and reproductive isolations are most closely associated with:
► Geographical isolation is the physical separation of two populations by geographical barriers. This occurs through adaptive radiation and allopatric speciation.
► Reproductive isolation is the separation of two populations of the same species, preventing interbreeding and production of fertile offspring.
Industrial melanism was highlighted in:
The peppered moth Biston betularia is also a model of parallel evolution in the incidence of melanism in the British form (f. carbonaria) and the American form (f. swettaria) as they are indistinguishable in appearance. Genetic analysis indicates that both phenotypes are inherited as autosomal dominants.
An isolated population of humans with equal number of blue-eyed and brown-eyed individuals was decimated by an earthquake. Only a few brown-eyed remained to form the next generation. This kind of change in the gene pool is called:
Hardy-Weinberg operates in the absence of:
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It operates in the absence of mutation, natural selection and recombination
