On the planet, PSEG, Rhinoceros Beetles are chosen for leadership positions in government based on their ability to sing Beetle songs. Most Beetles cannot sing at all (wild-type). A single autosomal gene, FRANK, with alleles F(dominant) and f (wild-type) determines whether the individual beetles have this singing phenotype. In a cross between two singing Rhinoceros Beetles, a large F1 progeny is generated. The ratio of singing Beetles to non-singing Beetles in this progeny is 2:1, irrespective of gender. The most likely mode of inheritance for the singing phenotype is:

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
