The coin sex lab was a lab done to demonstrate Mendel's sex laws like the law of independent assortment and segregation. Probability states that in a dihybrid cross, the ratio of phenotypes should be 9:3:3:1. In our experiment, we got a phenotypical ratio of 7:4:4:1. Although this is not exactly what the prediction is, it is close enough to the expected.
Although using genetics you can predict some traits of offspring it is not 100% reliable. When predicting traits, you are predicting the chance of having a trait. For example, by looking at the genotypes of parents, you can predict that the baby has a 50% chance of being colorblind, but you cannot be totally sure. This relates to life, because by knowing your genotype you can predict what traits your offspring may have.
Unit 4 was called "Why is sex so great?" It was about how two a sperm and egg produce a genetically different offspring. Some topics that we learned about were asexual vs sexual reproduction, chromosomes, sex cells, haploid vs diploid, meiosis and mitosis, Mendel's sex laws, genes and alleles (dominant/recessive) punnett squares, autosomal and X-linked inheritance, incomplete dominance, codominance, gene linkage, epistasis, and multifactorial disorders.
Some things I found difficult to understand were meiosis and mitosis. Some things I understood well were punnett squares and inheritance.
I want to learn more about is how mitosis and meiosis works.
I learned a lot about genetics and inheritance and more study techniques. I learned from the infographic that visuals help the learning process. I wasa better student in this unit because I managed my time efficiently and stayed on top of all of my vodcasts and notes.
The Vark questionnaire showed that I was more of a kinesthetic and visual learner than an aural and read/write learner. I was not surprised with my results because I remember more of visual information and learn a lot better from labs. To help me study for upcoming tests, I can draw pictures and study those to help me retain the information.
My results: Visual-9, Aural-4, Read/Write-3, and Kinesthetic-12
