This is an experiment where the researcher manipulates one variable, and control/randomizes the rest of the variables. It has a control group, the subjects have been randomly assigned between the groups, and the researcher only tests one effect at a time.
One result is that the ovaries would be unable to produce oocytes (eggs) for fertilization hence the woman would be unable to conceive. Another is that the woman would have an abnormal menstrual cycle due to abnormalities in the production of estrogen and progesterone by the ovary.
Drosophila melanogaster an excellent model for studying fundamentals of development because many of the genes involved in the development of the fruit fly are also found in humans and the precise formation of each of their 959 body cells has been mapped.
Its many of the genes involved in the development of the fruit fly are also found in humans. Drosophila melanogasteris which is also called Fruit fly is small in size and minimal requirements, many fly's can be raised and tested within a small laboratory which does not have access time, space or funding.
Genetic factors also make this fly an ideal model organism. Drosophila melanogasteris only has four pairs of chromosomes compared to 23 pairs in humans.
