Imagine you are a paleontologist and you found a plant fossil of a brand new species! What traits would this species exhibit for you to classify it as a bryophyte vs a fern vs a gymnosperm? Describe this hypothetical species's traits and your classification.
Homework Answers
by using following characteristrics chart once can classify the new plant found:
| characteristics | bryophytes | ferns/pteridophytes | Gymnosperms |
| vascular tissue | absent (-) | present (+) | higher level (^) |
| true leaves | (-) | (+) | (^) |
| stems | (-) | (+) | (^) |
| roots | (-) | rhizoids | advanced roots |
| pollen | (-) | (-) | (+) |
| seeds | (-) | (-) | naked seeds |
| fruits and flowers | (-) | (-) | (-) |
| water required for fertilization | yes | yes | no |

Question 13 1 pts In a hypothetical scenario, imagine that you have discovered a rare species of bird on a remote Pacific island. You spend some time studying their ecology and habitation and discover that although these birds look alike, they are indeed two distinct populations with very different mating calls. You propose that these two populations must be two species since they are no longer able to mate with one another. Which of the following species concepts would you...

You have identified a new species of flowering plant with red flowers instead of the usual blue flowers. You performed a cross and found that all of the F1 plants had purple flowers. When you self-fertilized these F1 plants, the resulting F2 was: Blue flowers: 1034 Purple flowers: 297 Red flowers: 94 What would the expected numbers be if these phenotypes were due to two alleles with incomplete dominance at a single loci? What if these phenotypes were due to...

Suppose your research team found a brand new gene that may be involved in the early stages of embryonic development. In studying this gene, your team manages to identify the promoter region and one enhancer region that is 1,000 kilobases upstream of the promoter region. To study this gene’s expression during embryonic development, would you choose to fuse a reporter gene, like GFP, with the promoter region or the enhancer of your gene of interest? Why would you choose that...
