Transposon can cause mutations in genes at or near the site of transposon insertion. it is possible for these elements to transpose away from their original site, causing a reversion of the mutant phenotype. in some cases, however, even more severe phenotypes appear when these elements excise from this site, due to events at or near the mutant allele. what might be happening to the transposon or the nearby gene to create more severe mutations?

Agenotype 'aa' leads to albinism in peacocks. this condition is very rarely found in nature, compared to the normal genotype, 'aa', and 'aa', as theycan be easy prey to their predators and are unable to attract mates. which types of selection forces act here? o a.directional selectionob. stabilizing selectionoc. sexual selectionresetnext© 2019 edmentum. all nights

When the grand canyon formed many small mammal population were divided. some members of the population were on one side and others are on the other, therefore, they were no able to mate with one another. over time this separation and inability to mate with one another led to the emergence of new species. this type of speciation is called a) sympatric speciation. b) allopatric speciation. c) parapetric speciation. d) peripatric speciation.
