Answer:

Parallel Evolution

Explanation:

It is because only three members are normal while one of them has a rare recessive allele.

Answer:

Bottleneck/ genetic drift

Explanation:

Bottleneck can be described as a situation whereby a  population of an organism is negatively affected through some certain events such as uncontrollable hunting of the specie,  destruction of habitat or environmental circumstances or disaster, and results to a reduction of the population.

Bottleneck is known to be a type of genetic drift, and its effect drastically reduces the population size of an organism. It also brings about a random change in the frequency of the alleles, which can be described as an evolutionary change.

In this case, what caused a reduction and evolutionary change of species of wildflower to mountain meadow is bottleneck.
