Unit 4 Reflection

       In Unit 4, we learned about the cell cycle, the different types of reproduction, the significance of chromosomes and how they relate to genes and traits, what Gregor Mendel discovered and his laws, meiosis, and finally punnett squares. This unit was mostly about the importance of sex, and throughout this unit my strengths was of the content in chapter 14 which was mostly about chromosomes. Even though I understood chromosomes, chapter 11 was a struggle for me because there was a lot of information with vocabulary words that I didn't know. From these experiences I learned how to focus on the vocabulary and the definitions of each one which helps build my understanding of this unit. Making the infographic helped me greatly when it came to the specific details from the vodcasts. I want to learn more about meiosis and mitosis (cell cycle) because it is very interesting learning about what the human body does to function.
       After taking the VARK Questionnaire, I received a multimodal learning preference in which the most scored style for me was the Read/Write in which I scored a 9. My results did not surprise me at all because from past experience I studied with different learning styles and altogether I tested the same. Using my reading and writing preference, I can prepare for the unit test by making flashcards and rewriting what I didn't understand. This concludes my Unit 4 Reflection.

Coin Sex Lab Relate and Review

       In this lab, we determined the different alleles, from each parents gene, for offspring by first writing a monohybrid/dihybrid punnett square or by drawing gene segregation, then flipping coins and recombining the new traits. The coins in the lab served as the heterozygous or homozygous genotypes from both gametes, which they only have haploid of chromosomes. My expected results for the dihybrid cross simulation was that there was at least going to be 1 homozygous recessive (bbee, 1/16, blond hair with blue eyes), 3 brown hair and blue eyed offspring, 3 blond hair and brown eyed offspring, and 9 brown hair and brown eyed offspring.Though after completing the dihybrid cross experiment, the actual result was only 1/16 (bbee) of the offspring had the non-dominant trait. Creating punnett squares to determine the offspring traits is the limit of using probability to predict our offspring's traits because we cannot pin-point each trait for each offspring. Understanding this relates to my life because when I choose to have a child, I can determine the probability of my offsrping having a specific trait. I can see if there is a certain disease my child can have that might be autosomal inherited or X-linked inherited. I can also relate this experience with my passion for math when I was figuring out the probability of the offspring's trait. This concludes my Coin Sex Lab Relate and Review.
