How are genetic characteristics associated with nonreproductive activities such as feeding affected by natural selection?
Use the hybrid selection model, OY = ky(1 - y)(a - by), to find the percent of the population that has the given characteristic.
dt
A research team is studying a population of snails to determine how quickly characteristic B will pass from one generation to the next. At the start of the study, 20% of the snails have characteristic B. After five generations, 81% of the population has characteristic B. Find
the percent of the population that will have characteristic B after eight generations. (Assume a = 2 and b = 1. Round your answer to the nearest whole number.)

Remember these are claims about why the trait for silk flexibility varies within the spider family. Claim 1: The offspring have mutations that affect their traits. Do we have enough evidence to support or eliminate any of the claims? WHY OR WHY Claim 2: The offspring's traits depend on which parent the offspring received more traits from. Claim 3: The offspring received different combinations of traits from their parents. NOT? Students, write your response! Pear Deck Interactarrow_forwardCan someone help explain this from a mathematicssl perspective?  Consider a species that occupies a large, but fixed, number of islands. The distribution of the species across all islands is maintained by a balance between local extinctions and local colonization events. Devise a model for the relationship between the fraction of islands occupied by the species and time. Be clear to outline the assumptions you make and be sure to describe your key predictions.arrow_forward

Â Â Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard. Â Â According to the hypothesis, the reason why the greenbeard phenotype is selected for is because the greenbeard individuals would preferentially receive altruistic benefit from non-greenbeard individuals. Â Â The reason why the "greenbeard" hypothesis is possible is because when direct fitness and indirect fitness are in conflict, it is always the factors that increase the direct fitness that will triumph over the factors increasing the indirect fitness. Â Â The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.arrow_forwardWhy are so few fossils of worms found?arrow_forward
