LAB REPORT :: essays research papers

Maury Matos1/14/02AIM Find out the mode of heritage from crossing brown big eyed male and little eyed female, and to find out the fenotype and genotype of offspring. I took the F1 data and traverse it with another congregation to find the F2 data.Hypothesis I think that the red eye have dominant traits over brown eyes, and big eyes have dominant traits over little eyes. I got to this hypothesis because the F1 data proves that red big eyes are dominant because the offspring have big red eyes indeed the traits of red eyes and big eyes had to be homozygous dominant.Materials1. Flies2. Vials3. Fly food4. Ether5. Q-tip6. MicroscopeProcedure1. Gather Materials.2. Take empty ampul and place all the flies in empty vial.3. Put ether in vial to put them to sleep.4. When they are asleep put them under a microscope to observe them.DataMaleFemalebrown big eyes - 0Brown big eyes - 0Brown little eyes - 0Brown little eyes - 0 personnel casualty big eyes - 134Red big eyes - 122Red little eyes - 0Red little eyes - 0ABAbaBababaAbBaAbbaabBaabb(prediction)MaleFemaleBrown sightless 12.5%Brown sightless 12.5%Brown big eyes 12.5%Brown big eyes 12.5%Red big eyes 12.5%Red big eyes 12.5%Red eyeless 12.5 %Red eyeless 12.5%(outcome)MaleFemaleBrown eyeless - 35Brown big eyes - 33Brown big eyes - 29Brown eyeless - 25Red big eyes - 32Red big eyes - 26Red eyeless - 32Red eyeless - 28Conclusion My hypothesis was correct, because I crossed the F1 data and came with the outcome. I guessed that red eyes and big eyes had dominant traits. When flies are crossed they gotta have their parents genes and in this case the parents genes.
