Answer:
The limitation of phylogenetic species concept is b. Evolutionary histories are not known for all species.
Explanation:
The species that share a common ancestor and have similar traits and functions are grouped together as a result of the phylogenetic species concept. The phylogenetic species concept shows a unique evolutionary history of one organism with another of the same group. The major set back in the phylogenetic species concept is the lack of evolutionary histories for certain species. So, these organisms cannot be grouped according to the phylogenetic species concept.
A Mutation occurring in the population will change the allelic ratio.
<h3>What is evolution?</h3>
Evolution refers to the changes that occurs in organisms over a long period of time such that those changes results in new species better adapted to their environment and having higher specialization.
One of the factors of evolution is mutation.
According to the Hardy-Weinberg principle, the allele and genotype frequencies of a population of organism in equilibrium will remain constant in the absence of evolutionary influences.
Therefore, if a mutation occurs in the population, the allelic ratio will change.
