A mutation exists in a gene that controls hair growth on the middle digit of human fingers. some people have mid-digital hair, w
hile others do not. the gene can be passed from one generation to the next. which explanation best predicts what should happen to this trait over time? the incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage. the incidence of mid-digital hair will increase because it offers no selective advantage. the incidence of mid-digital hair will decrease in the population because it has a selective disadvantage. the incidence of mid-digital hair will increase in the human population because it offers a selective advantage.
The best explanation that best predicts what happens to the trait over time is that the incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage. A mutation is a sudden, spontaneous random change that occurs in the genetic make up of an organism. The presence or absence of mid-digital hair is controlled by a single gene with two alleles, and the allele H is dominant.
