Thus, in this cross, all offspring will have the Bb genotype.

We are using fruit flies because they are easy to breed and it is easier to tell which genetic mutation that they have. The coloration of the abdomen is the easiest to recognize. This page was last updated on Tags:.

Each of these, however, requires low-cost equipment which can be easily purchased. Rapidly, insert an Alka-Seltzer inside the cup of water and seal the Ziploc bag.

inheritance patterns in drosophila melanogaster

Flynap, from Carolina Biological, is messy and has an odor that some find offensive. Even though all of the offspring have brown body color, they are heterozygous for the black allele. Can you establish a relationship between the proportions of progeny with certain characteristics?

An experiment testing the different inheritance patterns in the drosophila fruit

When flies are on the fruit, close the chamber, as shown in Figure 3. How is this possible? Each of these, however, requires low-cost equipment which can be easily purchased. Vial 2 contained wild females and white male, six of each. Crossing flies Once females are deemed virgins, add males. Do not allow media to dry out. However, the most useful characteristic of flies, particularly to human genetics research, is the close similarity between the genes of flies and humans. How do hidden genes pass from one generation to the next? Nearly two dozen Drosophila species have available genome sequences more on this below , of which D. Our project was using fruit flies and mixing certain type of breeds to see how it would affect the next generation by seeing what the sex and types of flies are produced.
