A) Fruit flies with a triploid set of chromosomes can exhibit new traits, such as eye color. B) Viable errors in DNA replication can lead to genetic changes that result in new phenotypes.
C) Changes to the genome can occur when fruit flies reproduce asexually to form new offspring.
D) Induced mutations occur in the genome when the DNA is exposed to radiation or other mutagens.
E) Chromosomal changes occur in sexually reproducing populations when homologous chromosomes pair up in meiosis.
