- What is meant by term Allelomorphs?arrow_forwardSuppose species 1, 2, and 3 are endemic to a group of islands (such as the Galápagos) and are all descended from species 4, an outgroup. We sequence a gene and find ten nucleotide sites that differ among the four species (among many other loci that do not vary). The nucleotide bases at these sites are Species 1: GCTGATGAGT Species 2: ATCAATGAGT Species 3: GTTGCAACGT Species 4: GTCAATGACA Estimate the phylogeny of these taxa by plotting the changes on each of the three possible trees and determine which tree requires the fewest evolutionary changes.

Species 1 and species 2 had a most recent common ancestor 50 million years ago.

The observation that multicellular individuals, like Volvox, have a much smaller subset of germ line cells compared to somatic cells appears to be general rule. Which of the following is the best evolutionary explanation for why this is the case? A) Organisms can biologically only contain a small number of germ line cells as they are always larger than somatic cells. B) Multicellular individuals with a germ line vs. somatic cell line differentiation only evolved a single time, thus all members of this lineage share the same scheme of more soma cells with a much smaller subset of germ line cells. C) Having a smaller subset of reproductive cells helps reduce the likelihood of cheating from evolving, which in turns prevents the collapse of the multicellular individual system. D) None of the above.arrow_forward

The ancestor of mitochondria and chloroplasts original became part of mutualism with a larger host cell. Which of the following best explains this mutualism? A) The mitochondria and chloroplasts provided specialized reproduction as part of the proto-germ line while the larger host cell provided energy for growth and reproduction. B) The mitochondria and chloroplasts provided gene products that could be used by the larger host cell for improved parasitization. C) The mitochondria and chloroplasts provided molecular energy in return for protection by the larger host cell. D) The mitochondria and chloroplasts produce toxins that the larger cell utilized to defend itself from other cells mutually increasing the defense of all those involved.arrow_forwardImagine you are studying two eukaryotic species. The genome of Species A is 100 Mb in size. The genome of Species B is 500 Mb in size. Based only on this information, which of the following statements are accurate? Species B is a more complex organism than Species A. None of the other statements can be made based solely on the information in the question. Species B has more genes than Species A. Species B has more chromosomes, more genes, and is more complex than Species A. Species B has more chromosomes than Species A.arrow_forward
