Read the entire article carefully, then answer these questions in complete sentences on a separate sheet of paper.
- Work duties for young bees include insert multiple words , while older bees insert multiple words .
- What is the name of the gene that turns stay-in-hive bees into foragers?
- Why was this gene already known?
- Dr. Sokolowski spent ____ years tracking down for, the gene responsible for the lazy fruit flies.
- Dr. Sokolowski also called the lazy fruit flies _________. You may remember this name when thinking of your lab partner.
- What are the ultimate biochemical products of genes (what do they eventually cause to be made in an organism) ?
- Dr. Sokolowski says 'the gene is less active' in the lazy fruit flies and that perhaps 'slight differences in the gene's sequence cause variations in its activity'. That means that ________________ cause changes in behavior. Wow!
- What do forager bees and wide-roaming fruit flies have in common ?
- "Expressing" a gene means the gene is apparent in the phenotype. For example, I was born with genes that lead to male-pattern baldness, but those genes weren't expressed until I was past my teenage years. Were the researchers able to show that the behavior change was as simple as the older bees expressing more of the for gene, so all that really mattered was the bee's age?
- What specifically does for make ?
- In the experiment with PKG, describe the manipulated variable and the responding variable.
- Why did the researchers treat bees with a similar chemical that didn't affect PKG?
- It is said that the process of evolution is 'conservative', it keeps good solutions. If it isn't broken, don't fix it. How does that idea apply to the for gene?
- List the colleges, universities or government research labs mentioned in this article.
