QUESTION 1

Maximum parsimony is one approach that is used to select phylogenetic trees that best fit the data. The idea behind this approach is to ________________the number of evolutionary steps (such as trait changes or amino acid changes) that would have led to the observed relationships between the taxa (e.g. species) at the tips of the tree.

maintain

eliminate

maximize

minimize

QUESTION 2

Traits that are detrimental to the long-term survival of an individual can occur in a population (select all that apply):

if they arise due to a mutation.

Never

when the trait increases an individual\'s chance of reproducing.

because there has to be variation in the population.

if they enter the population through gene flow from another habitat where the traits are favorable.

QUESTION 3

Only scientists need to be able to identify and distinguish species.

True

False

QUESTION 4

Post-zygotic isolation is always independent of the external environment.

True

False

QUESTION 5

Phylogenetic trees are hypotheses about the evolutionary relationships between individual organisms or species.

True

False

Solution

Ques-1: d. minimize

Reason:

Maximum parsimony is one approach that is used to select phylogenetic trees that best fit the data. The idea behind this approach is to minimize the number of evolutionary steps (such as trait changes or amino acid changes), character-state changes that would have led to the observed relationships between the taxa (e.g. species) at the tips of the tree. This maximum parsimony is going to depict that the optimal phylogenetic tree needs to minimize the exact amount of homoplasy of convergent evolution based on “trait changes” etc. Parsimony analysis is the method of identify the “evolutionary phylogenetic tree” with minor changes in its traits & the major the above occurrences are more problematic when using DNA sequencing data because “the evolution is slower” & due to more similarity in the characters observed in different species due to convergent evolution.

Que-Post-zygotic isolation is always independent of the external environment.

Answer: True
