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 potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
