Why is variation beneficial to the species but not necessarily for the individual?
Explain the concept of the pangenome to describe all distinct genes and variations in a species ?
In 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.

- Can you answer all the parts to this diagram Species 1 and 2 are sister species from which you’ve cloned related genes. On the gene tree on the top of the next page, use labels to answer the following questions: (a) Label the node that represents a gene duplication with “D,” (b) Label the nodes that represent speciation events with “S,” (c) Pick a pair of genes that are paralogs and label them both “P.” (d) Pick a pair of genes that are orthologs and label them both “O.”arrow_forwardDescribe five different scenarios where a change in DNA sequence would result in a phenotypic change at the organismal (human) level.arrow_forwardThe Forbes sea star and common sea star are broadcast spawners that are known to hybridize, yet they exist as separate, genetically distinct species (unique branches on the tree of life). One mechanism that may contribute to their uniqueness is prezygotic reproductive isolation, which is the incompatibility of gametes (sperm and eggs) from separate species. We know they hybridize, so the eggs and sperm are compatible, but could gametes from the different species be less compatible than the gametes from each individual species? Harper & Hart (2005) addressed this question in a series of cross-fertilization experiments. Did they find evidence that gametes ‘preferred’ to cross with gametes of the same species? Explain your answer.arrow_forward
- Imagine that Species A and Species B are closely related species. Species A has one hemoglobin gene, located on chromosome 5. Species B has two hemoglobin genes, one located on chromosome 5 and one located on chromosome 8. Based solely on this information, it is possible that the ancestor of Species A and Species B had one hemoglobin gene, and that a large-segment duplication followed by a translocation resulted in the second hemoglobin gene of Species B. True Falsearrow_forwardUse two different colors to depict the unduplicated chromosomes of species C with larger chromosomes (2n = 8) and species D with slightly smaller chromosomes (2n =10), and of their F1 hybrid.

How many chromosomes would you expect the hybrid to have? Would these chromosomes be homologous pairs? Dog-fox hybrids have occasionally claimed to occur, but none have ever been confirmed. If such a hybrid should ever be found, how many chromosomes would it have? Would these chromosomes be in pairs? Explain why or why not.arrow_forward
- Some species reproduce asexually (they do not undergo meiosis). What consequences do you think this will have for genetic diversity across the genes of those speciesarrow_forwardHelparrow_forward18) The common edible frog of Europe is a hybrid between two species, Rana lessonae and Rana ridibunda. The hybrids were first described in 1758 and have a wide distribution, from France across central Europe to Russia. Both male and female hybrids exist, but when the hybrids mate with other hybrids or with adults of either species, they are rarely successful in producing offspring. What can you infer from this information? A) Postzygotic isolation exists between the two frog species. B) Prezygotic isolation exists between the two frog species. C) These two species are likely in the process of fusing back into one species. D) The hybrids form a separate species under the biological species concept. 19) There is an island in the middle of a large river that houses a large population of ants. Damming of the river causes the island to flood and only the highest points of the island are now above water. The ants cannot swim, so are now in multiple isolated populations.

- If you were comparing the karyotypes of species that are closely related evolutionarily, what types of similarities and differences would you expect to find?arrow_forwardWhat is a Gene Pool? Explain?arrow_forwardYou want to make a phylogenetic tree of a group of three related species of lizards that live on an island. Their genome sequences are highly similar except for a gene that controls body size. In that region of the genome, one of the lizard species has one copy of the growth control gene (L1), the second species has a duplication of the growth control gene (L2) and the third species has three copies of the same gene (L3). The lizard species show an increase in size depending on how many copies of the growth control gene they have (L1 is smallest, L2 is medium-sized and L3 is largest). Is this enough information to determine the phylogenetic relationships between the species, and predict which of the species arrived on the island first (and is the ancestral species)? Yes, because the ancestral lizard genome probably had a single copy of the growth control gene and after arriving on the island it was duplicated, resulting in species L2, and then another duplication occurred resulting in…arrow_forward
