In a population of owl monkeys, allele t (tt and tt) codes for tufted tails. the frequency of allele t (tt), which codes for nontufted tails, is 40 percent. if a new predator starts catching the monkeys by their tufts and natural selection occurs, which of the following would most likely happen over time? no changes would take place because the allele governing tufted tails is not dominant. the frequency of allele t would decrease and the frequency of allele t would increase. the frequencies for the two allele forms would equal out. the frequency of allele t would increase.
