Before you watch this video you should really watch the previous video in the section which covers Types of Inheritance.
Pedigrees are graphical representations of ancestry with respect to one or more disease(s). Males are represented with a square while females are represented with a circle. The shape is black/filled in if the individual is affected by the disease. The shape is empty/white if the individual is not affected by the disease (may be unaffected or carrier). Usually each generation (row) is labeled with a roman numeral while each individual is labeled with a number.
Autosomal Dominant Pedigree
Autosomal Recessive Pedigree
X-Linked Recessive Pedigree
Mitochondrial Inheritance Pedigree
Now that you are done with this video you should check out the next video in the Genetics section which covers Purine Salvage Pathway & Lesch-Nyhan Syndrome.
my name is scott . you are amazing. I thank you so much. I have failed step 1 in part because I did not concentrate on high yield material. I under estimated the size of this exam. I am studying again for this monster. wish me luck.
Best of luck! I’m sure you will “stomp” all over the test this time around
I wanted to know if you use a webpage such as quizlet or utah webpath. let me know .

My genetics professor has left your link as a tool for us to use. GREAT RESOURCE!! Thank you!
I guess I’m not totally full of it LOL. Thanks for the comment Andrea!
Bruhh!!! Thank you soo much mann…. this stuff was very confusing to me but you made it bearable… with much practice i believe i will get it.
If a pedigree chart shows both parents dying (empty box and circle with a line drawn through them) do you assume that this is the result of the trait? Btw, thank you for the explanations and examples! They really help! I’m not taking Step 1 because I live in the Caribbean but your content is still helping me study for my upcoming test.
Very helpful!! Thanks a lot!!!!!
