In a population of lizards, we see the frequency of the allele that calls for green pigmentation increase from 50%, to 75%, and then 90% in three generations. Why might this be? 1. The brown lizards have a different breeding season.

2. The green lizards have a higher rate of reproduction.

3. The green trait is more favorable and increases chances of survival and reproduction.

4. The brown trait is more favorable and increases the chances of survival and reproduction.
