|
||||

|

This disjunction is more likely to be the result of? | Expansion of the species during glacial periods followed by the retreat of the southern population to high elevation habitats during interglacial period.

| Phylogeny reconstruction usually involves | Maximum likelihood, Bayesian Method, and/or bootstrapping
🗑
|
||||
| A rapidly evolving gene has limited utility in dating divergences that occurred a long time ago because such a gene | would accumulate multiple substitutions at identical nucleotides and would not reflect true divergence
🗑
|
||||
| if life originated on earth in the distant past and the evolved, we should see that | The first detectable traces of life on earth would be simple forms and only later would more complex and more "modern" forms appear

| Raabova et al. (2008) reported that the leaf length of haxaploid (6n) Aster amellus was 62.79 +/-26.91mm (1sd) when the plant were grown in their natural habitats. What can we infer from this specific result? | Approximately 95% of these hexaploid plants produce leaves between 8.97 and 116.61 mm

🗑
|
||||
| why doesn't a species adopt to the slightly different conditions just beyond its present range? | Because populations may lack genetic variation in one or more characteristics necessary for adaption and because populations at the range margin are usually isolated from those in the center of the range
🗑
|
||||
| What does it mean to say that mutations are random? | Whether a particular mutation happens or not is unrelated to how useful that h=mutation would be.
🗑
|
||||
| transposable elements | can alter the function of a portion and alter gene expression
🗑
|
||||
| Anueploids are usually produced | through nondisjunction in meiosis
🗑
|
||||
| biodiversity is higher in the tropics than in the temperate areas. this pattern may result from the trend that | Species carrying capacity higher in tropical area than temperate area; species diversification rate is higher in the tropical area than in the temperate area; time for specie diversification is longer in the tropical area than in the temperate area

|
||||
| evolution of diferent characters at diff rates w/in a linage | mosaic evolution
🗑
|
||||
| the lack of correlation between genome size and complexity of organisms | C-Valuse paradox
🗑
|
||||
| alternating periods of sloe and more rapid gradual change in an single lineage | punctuated gradualism
🗑
|
||||
| True or false: The # of sexes in all sexual reproducing organisms is a fixed character: 2, 1 male & 1 female | false
