Lab Test on Genetics of a Fruit Fly
ABSTRAT PAGE
We had to pick a lab to do and we had four choices. We could pick one on the how genes are pasted down from generation to generation.
FRUIT FLY
PURPOSE:
The purpose of this lab is to determine what genetics are dominant and which one is
recession in the fruit fly and to see what genetics are past down from generation to generation.
INTERODUCTUON: Mendel’s pea did and experiment that was demonstrates genetic inheritance. When his
experiment he found out that genes are past down from generation to generation. Mendel is
known more for his experiment on fruit flies and not on plants. With genes they are inside of the
centrosomes and a certain gene at the same spot with each chromosome and that is the locus. It is
crossing over in a fragment of the chromosomes. With the cross over id the directly in the
proportion to how far apart the chromosomes can be in the cell nucleus. Morgan was a person the
found out what genes were and he did not know anything about DNA. Morgan was a man that
made things happen and he laid down the ground work for people like Thomas Hunt Morgan to
come in and set the genetics in motion.
Fruit flies have been used for over 100 years for their genetics. Fruit flies share 75% of their
genes that can cause disease with the humans so the scientists can learn about the genetics in
humans by studying the fruit fly. Fruit flies are easy to take care of and they reproduce quickly
and they have so many generations that can be studied in a shorter amount of time. Fruit flies
only have four chromosomes but they are big chromosomes. Fruit flies are being used for genetic
models for human diseases like Parkinson’s and Huntington’s. Fruit flies soon will be in space as
a model there to look at them, scientist have to knock them out with a gas that has carbon dioxide
to put them to
