Question

For each situation, predict whether the allele frequency is likely to increase or decrease in the population due to natural selection. 1. A dominant allele is beneficial to individuals that carry it. a. The allele frequency will increase steadily until the allele becomes fixed. b. The allele frequency will increase rapidly, but the allele will not become fixed. c. The allele frequency will decrease until allele is lost. 2. A dominant allele is deleterious to individuals that carry it. a. The allele frequency will decrease until allele is lost from the population b. The allele frequency will increase rapidly, but the allele will not become fixed. c. The allele frequency will decrease, but the allele will remain in population. 3. A recessive allele in a population with some homozygous recessive individuals is beneficial to individuals carrying the allele. a. The allele frequency will increase steadily until the allele becomes fixed. b. The allele frequency will increase rapidly, but the allele will not become fixed. c. The allele frequency will decrease, but the allele will remain in population. 4. A recessive allele in a population with some homozygous recessive individuals is deleterious to individuals carrying the allele. a. The allele frequency will increase steadily until the allele becomes fixed. b. The allele frequency will decrease, but the allele will remain in population. c. The allele frequency will decrease until allele is lost from the population. 5. An additive allele is beneficial to individuals that carry it. a. The allele frequency will decrease until allele is lost. b. The allele frequency will increase steadily until the allele becomes fixed. c. The allele frequency will increase rapidly, but the allele will not become fixed. 6. An additive allele is deleterious to individuals that carry it. a.
