Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

How is a phylogenetic bootstrap value calculated? [ at least mention 3 points]
In the table below is a short gene sequence in 4 closely related taxa and an outgroup. Based on comparisons of this DNA sequence, determine the placement of these four taxa in the phylogenetic tree below. Clearly identify the taxon (P, Q, R, or S) that corresponds to each branch tip (1, 2, 3, or 4). Based on your constructed tree, is Species P more closely related to Species Q or Species S? Justify your answer.
For the first phylogenetic tree, if we assume absolute time is NOT represented, can we say that the species in circle B are more closely related than the species in Circle A? For the second phylogenetic tree (if we hold the same assumptions), can we say that B and C are more closely related than A and C?
I was given this and made a character matrix from it but I need help creating the most parsimonious phylogenetic tree for it.
