Corn Genetics Lab

Corn Genetics Lab



Conclusion / Results:
At the end of this experiment we learned a lot more about chi-square analysis and the dominant and recessive genes of corn. By being able to count the number of yellow, purple, shrunken, and smooth corn, we were able to conclude the ratio of genotypic ratio of 9:3:3:1.

By using the data gathered from our experiment and the chi-square values, were able to predict the parents of the corn. Here, we believed that the parents were black eyed and were Bb x Bb. We were also able to predict how the corn came to be by determining what kind of cross it was. We believed that the ear of corn was produced by a dihybrid cross (PpSs x PpSs) that involved two pairs of heterozygous genes.

In the end, our predictions were correct because we were able to determine the genes of the corn and their parents. This is important to us because we can use these genetics to figure out human ancestry and genetics. Genetics is a new, unique, and always changing world of molecular biology.

Review of Phylogeny EC

Review/Discuss Phylogeny What did I learn?: Through this activity I learned a lot more about phylogeny and the cladograms. For example, it is important to know the relationship of the lines and how they represent the amount of time that separates each species. This is important to know because it makes reading the cladogram much easier and we get to compare common ancestors and which species are related to each other. Through this activity I learned a lot more about phylogeny vocabulary such as the root, branches, and what each branch separation represents. It was also interesting to see how to tell different sequences apart and this is important because it helps us learn about how related two different species are. I also learned about SNP and Indels which are important to understanding mutations in DNA and how different sequences are made. Overall, I feel a lot better about phylogeny and learning about evolution now that I know the basics of cladograms. Answers to Worksheet

pGLO Lab Report

pGLO Lab Our experiments within the test tubes LB/AMP and LB/AMP/ARA Petri dishes, pGLO+ Our colonies of E.Coli Our dishes with the UV Light Our dishes without the UV light Conclusions / Results: This experiment turned out well because we were able to produce hundreds of E.Coli colonies in our pGLO+ LB/AMP/ARA dish. We learned about the production of DNA and how we can combine this bacteria, in this case E.Coli, with the GFP or green fluorescent protein. By doing this, we are able to see how quickly the E.Coli reproduces under certain circumstances. We used ampicillin (AMP) to kill the bacteria in the dishes without Arabinose (ARA). However, our dish with lysogeny broth (LB) in presence with arabinose, creates beta lactamase which is a resist protein to ampicillin. This also results in the expression of the GFP protein, giving the E.Coli its fluorescent glow in the UV light.
