Lab 7 student

Lab 7 student a sex-linked cross the mode of inheritance is determined when the mutant characteristic is associated with the X chromosome.

AP Biology Lab Manual Resource Center

The experiment will take several weeks. After one day the eggs hatch into the larva. Sex the adult flies and write down any mutations. Next, these are the steps for immobilizing the flies. Methods Begin by obtaining a vial of wild type flies. They get darker in about an hour.

At room temperature the average life cycle of the Drosophila is about 12 days. There are three types of crosses that are studied in this lab. Place the flies in the morgue that contains alcohol.

In order to analyze your Lab 7 student you will first have to be able to be able to complete Chi-Square Analysis. In particular, the eyes, the wings, and the legs become visible.

You will be assigned Drosophila with well-defined mutant traits by your teacher. In a dihybrid cross the mode of inheritance is determined when the two pairs of contrasting of characteristics are considered simultaneously.

Materials The materials used in this lab are as follows: They are fragile and light in color and their wings are not fully expanded.

Make sure that the first flies you use are virgins. The last larval covering then becomes harder and darker, forming the pupal case. After she mates her receptacles contain large amounts of sperm and she lays her eggs. They are easily located in the large salivary glands.

Drosophila has a small number of chromosomes, four pairs. When metamorphosis is over, the adult fly emerges form the pupal case.

Once again, after another week has passed remove the F2 flies and record their sex and characteristics and place the results in Table 7.

Make sure to examine the flies and determine the characteristics of their eyes, wings, bristles, and antennae. Next, get a vial containing experimental flies. Practice immobilizing and sexing these flies. Eggs of the Drosophila are small, oval shaped, and have two filaments at one end.

Use the dissecting microscope to view the flies. When the flies are immobilized, place them into a small plastic Petri dish. The F2 generation are the eggs and larvae in the vial.Lab Lab Arrays Arrays Arrays and Functions and Functionsand Functions Copy and paste the following program into Visual Studio IDE.
