Title:
How many times does the “eyes absent” gene occur in 50 generations.

Topic:
The main scientific idea is to see if over many generations of fruit flies when given less and less food if genetic mutation occurs more often.

Purpose:
I chose this topic to investigate because I was curious about how many genetic mutations would occur in fruit flies over 50 generations when given less and less food and link this to genetic mutations with humans and starvation.

Problem:
How does the ofteness of genetic mutations in fruit flies match up with the same genetic mutation in humans?

Research:

Information: This website shows the many different common genetic mutations that occur among fruit flies. Mutations can be good or bad, but the majority of the time mutations can be neither good nor bad.

Information: “Researchers have by means of genetic breeding, changed a two-wing fruit fly into a four-wing fruit fly. The four-wing fruit fly consistently reproduces four-winged fruit flies. But although a new species has been produced, it is not a new “kind.” The mutant fruit fly is still a fruit fly. As a matter of fact, the four-winged fruit fly is a weakened form. The second set of wings do not help the fruit fly; they actually get in the way. Its ability to take flight is dangerously hindered. Having been selectively bred in the laboratory, this species will also not survive without the caring assistance of researchers. This is a poor example of evolution by mutation. The bottom line is that mutations always weaken an

Information Processing To understand and explain consumer responses to coordinated television-web (TV-W) campaigns, we should understand the processes behind the ad encoding and retrieval. According to Edell and Keller (1989) each sensory mode used (e.g. audio, video) has ability either to evoke direct cognitive or affective responses or serve as a distraction to other modes. A typical TV ad uses multiple sensory modes by combining audio and video at the same time. The multimode nature of TV could…

Experimental Research Designs Essay

Experimental Research Designs “A correlational study determines whether or not two variables are correlated. This means to study whether there is an increase or decrease in one variable corresponds to an increase or decrease in the other variable” (Cherry, 2012). In most correlation studies there is a relationship between both variables that had a change, while in others there wasn’t necessarily causation between the two (Cherry, 2012). An experimental design is one in which the researcher manipulates…

Research Paper

validity asks the question: do the conclusions that we draw about a demonstrated experimental relationship truly imply cause? External validity asks the question: does an observed causal relationship generalize across persons, settings, and times? Each type of validity has specific threats. Threats of internal validity are history, maturation, testing, instrumentation, selection, statistical regression, and experimental mortality. When it comes to history, during the time an experience is taking place…

entering the cafeteria. The research was able to show that this treatment was effective in helping the girl to stop her spoon banging behavior (Horton, 1987). After reading through the different case studies I find this one to be more like Single-case design because “Researchers describe, predict, and control variables in order to understand and treat the behavior of one individual.” (Zechmeister, 2001) This uses the Scientific Method by observing all aspects of her behavior, manipulating the variable…
