| Video Discription | Explore how to solve Punnett squares that involve sex-linked traits, specifically focusing on X-linked traits. Video has a resource available here https://www.amoebasisters.com/handouts This 2023 UPDATED sex-linked traits Amoeba Sisters video has more detail and improved art from the old 2015 Punnett squares and sex-linked traits Amoeba Sisters video. OLD VIDEO: https://youtu.be/h2xufrHWG3E ----------- Table of Contents: 00:00 Intro 0:49 Sex Chromosomes 2:25 Solving Sex Linked Punnett Square Problem 5:40 Five Things to Keep in Mind ------------- *TEXTBOOK REFERENCES* Clark, Mary Ann, et al. “12.2 Characteristics and Traits - Biology 2e | OpenStax.” Openstax.org, 28 Mar. 2018, openstax.org/books/biology-2e/pages/12-2-characteristics-and-traits. Urry, Lisa A, et al. Campbell Biology. 11th ed., New York, Ny, Pearson Education, Inc, 2017. ---------------------------------------- *ADDITIONAL DETAIL INFORMATION* *More info on Hemophilia: https://www.cdc.gov/ncbddd/hemophilia/facts.html *More about red-green colorblindness & other forms of colorblindness: https://my.clevelandclinic.org/health/diseases/11604-color-blindness *Biological sex described by NIH & Yale School of Medicine: NIH: https://orwh.od.nih.gov/sex-gender Yale School of Medicine: https://medicine.yale.edu/news-article/what-do-we-mean-by-sex-and-gender/ *Footnote about "male" & "female" terminology from NIH at BOTTOM of https://orwh.od.nih.gov/sex-gender/sex-and-gender-in-health-and-disease ^^Above sources also explain difference of sex & gender. *This video is about traits on sex chromosomes. In most cases, females have XX chromosomes & males have XY chromosomes BUT as video mentions, this is not always the case. Examples: XXY: https://www.genome.gov/Genetic-Disorders/Klinefelter-Syndrome XYY: https://medlineplus.gov/genetics/condition/47xyy-syndrome/ X: https://www.genome.gov/Genetic-Disorders/Turner-Syndrome Info about SRY gene & also conditions related to variants in SRY gene: https://medlineplus.gov/genetics/gene/sry/ ---------------------------------------- *FURTHER EXPLORATION* 1. How did X and Y sex chromosomes get their names? From Arizona State University's "Embryo Project Encyclopedia" https://embryo.asu.edu/pages/sex-determination-humans 2. Preeclampsia was mentioned as an example that many disorders may have a genetic component yet are NOT single gene traits (and thus can't be easily worked on a Punnett square). In addition, many disorders may involve autosomes and other external factors. As mentioned, the cause of preeclampsia is currently not well understood though gene involvement is being studied. *Genetic Risk Factors: https://jamanetwork.com/journals/jamacardiology/fullarticle/2805948 *Recent News regarding Preeclampsia: FDA clearance of Preeclampsia risk assessment assays: https://www.preeclampsia.org/the-news/research/thermo-fisher-scientific-gets-fda-clearance-for-preeclampsia-risk-assessment-assays *Preeclampsia Foundation's Page of Research News: https://www.preeclampsia.org/the-news/research-news 3. Sex chromosomes in other animals can vary & may not be able to be worked in same type of Punnett square: Sex chromosomes in birds? Written by a professor of genetics: https://theconversation.com/how-birds-become-male-or-female-and-occasionally-both-112061 Platypus: https://www.pnas.org/doi/10.1073/pnas.0405702101 ----------------------------------------------- The Amoeba Sisters videos center on Pinky's certification and experience in teaching biology at the high school level.
