Lungfish have two alleles for a gene, B and b. The frequency of B in a population living in pond 1 is 0.2. The frequency of this allele in pond 2 is 0.8. Lungfish migrate from pond 1 to pond 2 such that 10% of the pond 2 parents in the next generation are migrants from pond 1. What will be the pond 2 allele B frequency in the next generation

The sketch shows a rynchosaur, an extinct animal that is known only from fossils. there has been much debate about the classification of these creatures. some scientists suggest that they belong with primitive amphibians, and some think they are related to snakes and lizards. the data equally support both cases. which statement best explains how to draw a cladogram that includes the rynchosaur? draw the cladogram for amphibians. draw the cladogram for reptiles. draw two cladograms, both showing the traits, and leave it as a hypothesis. draw two cladograms, both showing the traits, and have scientists vote
