The statement that indicates "monophyletic refers to a given taxon which includes an ancestral species and all descendants" is TRUE.
What is a monophyletic group?A monophyletic group is a taxonomic group composed of an ancestral species and all descendants of such species.
Monophyletic groups form specific branches of biodiversity that can be diagramed in the tree of life.
These diagrams represent evolutionary relationships and they are called cladograms (phylogenetic trees).

How many chromosomes are present in the cell before the start of meiosis?.
Answer: 46
Explanation: 46 chromosomes are present in the cell before the start of meiosis.
The number of chromosomes that are present in the cell before the start of meiosis is 46. Because the total number of chromosomes in a human cell is 46.
What are chromosomes?Chromosomes are the thread-like structure present in pairs in all organisms. They are present inside the nucleus, and contain genes and DNA in them, and are responsible for the traits of an organism.
Meiosis is a process completed in two stages, and each contains four phases. It occurs in the germ cells, divides the cell into four cells, and reduces the number of chromosomes.
The number of chromosomes in humans is 46, 23 in pairs. Before meiosis, the number of chromosomes will be 46 after Meiosis the number reduces.
Thus, there are 46 chromosomes in the cell prior to the onset of meiosis.

explain how natural selecin oacting on allele frequencies of a gene that controls body coloraiton can result in populations of 3 different species
Answer:
Answer below
Explanation:
Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.
