You observe a population of Island Sparrows for which the phenotype of crown color varies from yellow to white. You perform two experiments. Experiment 1 shows that this variation in the phenotype affects mating success, so that birds with yellow crown colors have more offspring. Experiment 2 shows that this variation in phenotype is determined fully by the diet of the birds and not genetics. Crown color will evolve via natural selection in this population of Island Sparrows.
1. True
2. False

From Experiment 2, it is clear that the color of the crown does not depend on the genes. It depends only on the food taken by the sparrow. Experiment 1 proves that yellow people have higher reproductive success. Those with yellow crowns have good skills in finding food. Depends on hunting / feeding vision, hunting skills, body muscles, etc. These genes are determined in whole or in part.
The Yellow Crown Sparrow contains the gene for their offspring. These offspring get genes that are very good at finding food so that they can get the food they need. They need a yellow crown. Ends
White-crowned sparrows are not good at finding food. They produce a small number of offspring that are not enough to find food. Lack of proper food, resulting in a white crown, results in a small number of offspring.
Over time the sparrow crown develops in the yellow direction. This is due to differences in hunting / feeding skills. This difference leads to natural saliva.
