Apopulation of green beetles (gg; gg) lives in a specific habitat. the allele for color is represented by the colors on their backs. over time, through random chance, the gene pool of the beetle population changes and more brown (gg) beetles are present in the population. how would you describe the sequence of events that lead to a change in allelic frequency? a) mutations within the population occurred. the brown allele (g) spread throughout the population of beetles. b) beetles with the brown allele immigrated into the population; the beetles mated and reproduced, incorporating the recessive allele into the gene pool. c) brown beetles had a survival advantage over the green beetles. over time, the brown allele increased within the beetle population and the genotype became gg. d) the beetles' habitat changed over time. the green beetles were the victims of predators and the brown beetles were not. over time the allelic frequency changed and the gene pool became gg.

Because of genetic variation, a species of beetle has two different body colors, red and green. this species exists in a grassy environment that’s mostly green. a new species of bird that eats these beetles enters the area. arrange the steps of natural selection in the correct order. tiles green beetles and red beetles exist in the environment. green beetles pass on their color trait to future offspring. birds that eat the beetles move into the environment. red beetles are eaten by birds, but green beetles aren’t eaten. the entire population of beetles eventually becomes green in color.

Sort the mutations based on whether their effects are harmful, beneficial, or neutral to the organisms that experience them. a mutation that increases the ability to store moisture in a dry environment a color mutation that decreases a bird’s chances of sexual selection a mutation in a noncoding region of dna a mutation in a gene that does not change protein synthesis increased white pigmentation on a prey animal in a snowy environment a mutation decreasing a plant's height in competition for light reset next
