Punnett square

Fruit flies are used in genetics and biological research because they are cheap and be quickly cultured. The use of the Pearson’s fly lab was pre-assigned for the physical experimental procedures to produce results in a limited time frame and reduce the chance of fruit flies contaminating the lab from student error. In order to test the hypothesis, I would observe the F2 generation. The initial parent cross takes approximately two weeks prior to produce the F1 generation. This parental cross…

Worms. Big worms, small worms, slimy worms. You may not think about worms every day and you might not care for them, but some worms actually play a great role in science. I’m talking about C. elegans. These microscopic worms are being investigated by scientist all the time. They were discovered in the 1970’s by Sydney Brenner and currently an international consortium of laboratories are collaborating on a project to sequence the entire 100,000,000 bases of DNA of the C. elegans genome (CBS). So…

carrier of Duchenne muscular dystrophy (XAXa) and her husband is not Duchenne muscular dystrophy (XAY). What is the probability their child will be duchenne muscular dystrophy? 9 Provide the solution to your problem. Include text and/or a Punnett square table explaining your solution.Include the appropriate probabilities. Answer: 25% Mother Father XA Y XA XAXA XAY Xa XAXa XaY Because DMD is a sex-linked recessive disorder, the only chance their child will have…

Gregor Mendel the famous scientist who experimented with pea plants to get a better understanding of genetics. As much work he did with pea plants he was also a botanist. His observation became the root of the study of heredity. His work showed that genes in pea plants follow certain patterns. Like all experiments Mendel had to have a hypothesis, the experiment and the results. Gregor Mendel experimented with genetics to understand why offspring look the way they did. He started his experiments…

Trev Mumm and Peter Masinelli Life 120 – Lab Section 122 April 28th, 2014 ABSTRACT We completed this lab to classify and count phenotypic traits in plant crosses with one or two segregating mutations, and we also learned how to use the Chi-Square test as a tool to access the statistical significance data collected from a genetic cross. Our hypothesis for the experiment that included green and albino corn genetics, was that the ratio of green to albino seedlings would be 3:1. Our…

PURPOSE The purpose of this lab is to acquire the ABO blood type of four unknown individual’s samples through a series of steps. Blood typing consists of a test in which ultimately determines an individual’s blood form. This procedure is an essential process for those who need blood transfusion or those willing to donate blood. The reason this stage is compulsory is because not all blood is compatible. Potentially a fatal transfusion reaction can occur if a unit of blood containing an ABO…

Kittens from the same litter can look different for a multitude of reasons. The reason each kitten looks different is contained in the genes of each kitten. The genes are located inside the kitten’s 38 chromosomes. Half of the kitten’s chromosomes are inherited from his or her mother, while the other 19 are inherited from his or her father. DNA is tightly coiled inside of each chromosome, and the chromosomes contain genes which are comprised of proteins and nucleic acids, specifically Adenine…

the chromosome, one from each parent. Each copy is called an allele. Many homozygous genotypes parents were more closely related less genetically diverse. More heterozygous genotypes were distantly related more genetically diverse. We can use a punnett square to predict the probability of genotypes of offspring. How non-heritable traits affects me is I have hair on my arms and my dad…

result for the F2 offspring, six would minus one therefore the the number of degree of freedom being used for the lab report would be five degree of freedom. The Chi square number for the fruit flies problem is 0.795. The number 11.072 determined whether the hypothesis is supported or not supported because based on Chi square 5% or less is not supported while a higher percentage of five is supported by the hypothesis. The hypothesis for the genotype and phenotype of the fruit flies was…
