What can be said about the fitness of wild steelhead trout populations and captive-bred steelhead trout? (see figure above)
The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
This data does not help us understand effects of gene flow on fitness.
The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.
The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.

- Describe an example of natural selection acting on new DNA patterns to select the most advantageous characteristics.arrow_forwardWhich of the following statements about the "greenbeard" effect is correct? Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard. 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. 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. The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.arrow_forwardExample: Suppose you wish to lose 4.54kg either through physical activity or by dieting. 1-How long would you have to work at an activity of 15Kcal/min to lose 4.54kg of fat?arrow_forward

The favorable to be passed on are chosen by the breeder to create a new or improved variety. Farmers have bred like corn, to produce more food in a smaller area. These plants result by crossing parent plants for their desired traits. animals, like dog breeds, have also been bred to be incredibly compared to the diversity of their ancestors. This selecting of traits is also known as selection. Similar to natural selection, the of a species changes over time, and some traits become more common.arrow_forwardIdentify two density dependent factors that could act as limiting factors for a population .
