**Need help with the VOCABULARY in this video? **
If you need a refresher, we recommend this glossary of key terms here by the free, peer-reviewed OpenStax Biology Textbook. https://openstax.org/books/concepts-biology/pages/8-key-terms

**We mention to check the video description for the section on sex-linked traits, because although this part focuses on sex-linked traits in Punnett squares, sex determination is more complex than chromosomes sexual alone. Here are some readings we recommended in our gender traits video on this topic:
*About the NIH SRY gene: https://ghr.nlm.nih.gov/gene/SRY
*About SRY and sex determination at Harvard: https://sitn.hms.harvard.edu/flash/2016/im-xy-know-sex-determination-systems-101/
*What about cases where individuals have different combinations of sex chromosomes, as mentioned in the video? Two examples include Klinefelter syndrome and Turner syndrome. More information on this from the NIH:

SUGGESTED FURTHER READING:
Why learn genetics? Learning about genetics helps us understand inherited traits in all kinds of organisms, including plants (like crops) and animals (like humans).
For an example of plants, did you know that there is a fungus that threatens the supply of bananas? Find out how scientists are using their knowledge of genetics to solve this problem: https://www.nature.com/articles/d41586-019-02770-7
To take humans as an example, the study of genetics helps us understand how our own traits are inherited. We can also help you learn more about genetic diseases and how they can be treated. Our video mentions the genetic disease, hemophilia. Did you know that gene therapy is currently being studied in human clinical trials? Learn more from the National Hemophilia Foundation: https://www.hemophilia.org/bleeding-disorders-az/treatment/future-therapies/frequently-asked-questions and learn more about the disorder here https:// www.hemophilia. org/hemorrhagic-disorders-az
Remember when the Human Genome Project ended in 2003? Did you know that there was still a percentage whose sequencing had not been completed? Learn more from the NIH here https://www.genome.gov/about-genomics/educational-resources/infographics/Completing-the-human-genome-sequence and see the infographics at the bottom. Here is general information from the NIH on the Human Genome Project https://www.genome.gov/human-genome-project
