In our evolution case study, the bird population initially had three beak size phenotypes--small, medium, and large. Following the drought, you correctly predicted that the next generation would have exclusively large and medium beaked birds as the smallest food source had died out. Which of the following accurately describes why there were no small beaked birds in the next generation?

In our evolution case study, the bird population initially had three beak size phenotypes--small, medium,
and large. Following the drought, you correctly predicted that the next generation would have exclusively
large and medium beaked birds as the smallest food source had died out.
Which of the following accurately describes why there were no small beaked birds in the next generation?
The birds with small beaks mutated to have large or medium beaks because that is the more beneficial
phenotype
for their environment.
The small beaked birds died and thus didn't contribute alleles for small beaks to the next generation.
The small beaked birds migrated to an area with better food availability.
The small beaked birds died randomly.
