Question

Researchers can use molecular homologies to __________

Answer 1

Researchers use molecular homologies to accurately describe phylogenies, which involves analyzing DNA sequences to determine evolutionary relationships and construct phylogenetic trees.

Step-by-step explanation:

Researchers can use molecular homologies to describe phylogenies accurately. Molecular homologies are sequences in DNA that are similar due to shared evolutionary history. By comparing these sequences, researchers can use computational tools and databases such as GenBank to determine the evolutionary distance between organisms and construct phylogenetic trees that reflect genetic relationships.

Molecular systematics allows researchers to differentiate homologies from analogies, where homologies are traits inherited from a common ancestor, and analogies are similar traits that evolved independently due to similar selective pressures, referred to as homoplasies.

Answer 2

Step-by-step explanation:

Researchers can use molecular homologies to reveal the number of mutations in a particular sequence that has occurred in each species since they diverged from a common ancestor
