Discuss the phenomenon of polyploidy and explicitly demonstrate how it can contribute to the process of speciation.

Discuss the advantages and limitations of the morphological species concept in defining species.

Explain Aneuploidy in the Human Population?

Besides the ones mentioned in this textbook, look for other examplesof variations in euploidy. Perhaps you might look in moreadvanced textbooks concerning population genetics, ecology, etc.Discuss the phenotypic consequences of these changes.

Prezygotic isolating mechanisms prevent hybrid offspring from occurring between species because (a) the resulting offspring are not fertile and cannot reproduce. (b) the egg and sperm fuse and form a zygote, but it does not survive. (c) the egg and sperm do not ever meet or, if they do, cannot fuse to form a zygote. (d) all of the above

Morgan and colleges were ultimately able to identify 4 linkage maps in fruit flies. How many pairs of chromosomes do fruit flies have based on those data?     2     8     6     4

which statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.

Which reproductive barrier is most likely to prevent interbreeding between a polyploid species and its diploid sister species?

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.”

6 Create a concept map using the following terms/concepts: sympatric speciation, polyploid speciation, habitat differentiation, sexual selection, autopolyploid, allopolyploid. Add definitions for each term/concept and make connections where necessary.
