Answer:

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

In which of the domains would it be easiest to determine the phylogenetic relationships among organisms?
ioda

The study of relationships and the evolutionary history of various groupings of species is known as phylogeny. The goal of phylogeny is to reconstruct the evolutionary course of all species on Earth. A phylogenetic tree also learned as a cladogram, is a schematic diagram used to show the alleged evolutionary relationships between taxa. Diagrams of phylogenetic trees are based on cladistics, or phylogenetic systematics, hypotheses.

Organization of life, according to taxonomy, divides creatures into three domains:

  • Bacteria
  • Eukarya
  • Archaea

The Eukarya domain are the most easy because they are large enough for their morphological features to be easily seen.
