Explain the biological species concept. Why is it not a
perfect definition of a species?
. In a phylogenetic or evolutionary tree, how is relatedness defined, i.e., what is used to determine relatedness?
Provide details of a mechanism that can result in the creation of new genes, with novel functions, that may contribute to the evolution of new species. Give a specific example.

- What is meant by the term “common ancestor”? Give an example.arrow_forwardWhy is variation beneficial to the species but not necessarily for the individual?arrow_forwardSpecies A has 2 n = 10 chromosomes. Species B has 2 n = 40 chromosomes. On average, will two randomly selected genes from species A be more likely, less likely, or equally likely to assort independently than two randomly selected genes from species B? Explain your reasoning.arrow_forward
- Describe the biological species concept and list two potential problems with the concept.arrow_forwardExplain the following phrase: Degrees of molecular similarity correlate to degrees of species relatedness.arrow_forwardDiscuss the advantages and limitations of the morphological species concept in defining species.arrow_forward
- what notion is common to each of the species concepts?arrow_forwardIn sexually reproducing species, each individual begins life with DNA inherited from both parent organisms. , Apply this idea to what occurs when organisms of two species that have homologous chromosomes mate and produce ( F1 ) hybrid offspring. What percentage of the DNA in the F1 hybrids' chromosomes comes from each parent species? As the hybrids mate and produce F2 and later-generation hybrid offspring, describe how recombination and natural selection may affect whether the DNA in hybrid chromosomes is derived from one parent species or the other.arrow_forward(d) Scientists believe that the yellow fern arose from hybridization with another fern on the island. Create a diagram of this hybridization that tracks the origin of the chromosome number in the yellow fern.arrow_forward
- Describe five different scenarios where a change in DNA sequence would result in a phenotypic change at the organismal (human) level.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_forwardMolecular marker is used to determine relatedness of species which may directly or indirectly exerts an effect on diversity. A hypothetical ancestor has the following DNA sequences: G A A G C T A T T C A T T. There are two lineage with DNA sequences of G A A G G T A T T C T C G, and G A A C C T A T T C T G C. (1) Determine the percentage of A and T in the DNA sequence of the hypothetical ancestor. (2) Calculate the percentage of each nitrogenous base in the second lineage.arrow_forward
