Introduction: “Gregor Mendel was born in Neu-Titschein, Czecho-Slovakia. Certain men of science in Czecho-Slovakia, particularly in his native province, are seeking to establish a monument to him.” (Chas. B. Davenport) Gregor Mendel developed a model that shows the several characteristics of organisms. These characteristics were known as “traits.” Today we call them “alleles.” Mendel discovered an amazing statement. The way we are born is not randomized. There are different percentages of chance on how each phenotype is recreated. Mendel conducted his experiment by using pea plants because they were so easy to grow and take care of. “The peas used by Mendel for hybridization differed in the simplest case only by one character or, better still, …show more content…
The methods of the procedure was very simple but took quite a bit of time. The flies that were given to us to look at were offspring of the wild type and the mutant fruit fly. The wild type has red eyes, tan body and normal wings while the mutant had brown eyes, black body and reduced wings. To begin with the experiment we put a couple of the wild type flies asleep using “fly nap” just to figure out what alleles the flies had. We did the same thing with a couple of the mutant flies. We inspected the fly to see what kind of alleles it had so we knew what to look for in the off spring. The next thing we did is took the jar of flies that were given to us and put them all to sleep of what we could get from the jar. We the sorted each fly into the correct phenotype it belonged to. We tallied the count in table 1. We then waited a whole week. The next lab that we came to we tried to get more from the jar. The flies were still hatching and producing more and more. We then took what we could from our jars and put the flies asleep and sorted them again. We were supposed to collect around 100 flys but ended up only counting 53. We then made 2 figures and 1 table of our results. The results were exactly as we hat we predicted they would be. The amount wild types we found are 13. The amount of mutant replicas is 17. The amount of flies that had a tan body, reduced wings and brown eyes is 4. The amount of flies that had a black body, normal wings and red eyes is 3. The amount of flies that had a tan body, normal wings and brown eyes is 4. The amount of flies that has a black body, reduced wings and red eyes is 8. The amount of flies that has a tan body, reduced wings and red eyes is 3. Finally, the amount of flies that had a black body, normal wings and brown eyes is 1. We expected a slow decrease on possibilities as we go down the list. This is why the last one has a double cross

His career started at a conference he attended where they gave away samples of high-quality DNA. When Wilkins took this DNA sample back to his lab he had his student, Raymond Gosling, look at the DNA with new technique called X-ray diffraction. Another scientist, James Watson was also in this quest to figure out DNA. Watson ended up going to a conference where Wilkins was presenting his findings…

Mendelian Genetics

Lab 2: Mendelian Genetics Why do you share traits similar to the ones that your parents have? Why is it that a certain trait that your father has was passed to your siblings, but not to you? These questions were asked for hundreds of years. Traits are simply different forms of a character. For instance, AB and O are two different traits for the character blood type. Black hair and blonde are two different traits for the character hair color. Heredity is the passing of traits from the parents to…
