About this listen

Do you find yourself mesmerized by all the little details in the world around you? Do you love biology and think life is fascinating? If you're an AP Biology student or someone who just wants to delve into biology, I'll teach you AP Bio's concepts! Let's dive in! Credit: I use Sara Downs's Getting Down With Science (2020) resources and my own notes that were created using the Biology for the AP Course textbook by James Morris et al. and Barron's AP Biology book.

    Error 1: I meant to say "eukaryotes" instead of "karyotes" at 18:04.

    Error 2: While discussing X-linked trait inheritance patterns on pedigrees, I forgot to mention tips on how to recognize X-linked dominant traits! Here are some tips on how to identify X-linked dominant traits on pedigrees from the following website: https://migrc.org/teaching-tools/genetic-inheritance-patterns/sexx-linked-dominant/

    "After filling in the genotypes for individuals in several family trees that exhibit this mode of inheritance, some patterns that can be noticed are:

    • All daughters of a male who has the trait will also have the trait.
    • There is no male to male transmission; the trait follows the inheritance of the X-chromosome.
    • Sons can have the trait only if their mother also has the trait.
    • Same inheritance pattern as autosomal dominant traits in human females" (para. 2).

    Error 3: I meant to clarify this in the episode, but "chiasma" refers to one location of crossing over in prophase 1 whereas "chiasmata" refers to multiple locations of crossing over in prophase 1.

    I hope this helps you guys!
