Genetics

I've always found genetics to be a very interesting topic. To think that Gregor Mendel began to get a handle on inheritance long before scientists had any notion of chromosomes or DNA, is quite astounding. The march of progress has taken us from humble pea breeding to full on genetic sequencing, gene therapy, and microarrays. 

I am a bit tardy in submitting this post, but since the students just took their test yesterday it is still absolutely relevant. So, without further adieu here is a review of 2/6-2/10 submitted by Montana Hicks and Imran Shah.

This past week we began our study on Genetics and Heredity. I think it is safe to say our brains are overwhelmed. We have discussed how genes, traits, and diseases are passed down generations as well as completing pedigrees of traits in families. I would have to say the topic most interesting to me is the diseases and how they are actually passed down. In doing the pedigree activity I felt I was better able to understand the concept. It broadened and got us deeper into the passage of genetically connected diseases.We took a scenario and completed what could be the possible generations traits due to the family history. Throughout this week I feel that personally I learned a lot and it has helped me with the upcoming genetics project!

Imran Adds:

On the week of February 6th-10th we started off the week with the Mendelian Process, and its dealings with the inheritance of traits and dominant and recessive allele’s. We started with the review of monohybrid, and dihybrid crosses, and how we could use them to determine phenotype and genotype of homozygous and heterozygous alleles, as well as complete, and incomplete dominance. We then discussed pedigree charts, crossing over, and X and Y linked genes. We then came across Lab 5, an experiment involving the breeding of fruit flies, in which we selected and followed their traits. Lastly we discussed out reading for Thursday night, the Central Dogma of DNA, tracing the process of DNA Replication.
