X-Linked Pedigrees MADE EASY

My goal is to reduce educational disparities by making education FREE.

Some videos contain mild profanity and hyperbole solely used to assist with memorization. Viewer discretion advised.

The pedigree examples at the end (example #1 and #2) were not proofread by a geneticist. I made them quickly just to illustrate visually what rule #1 and rule #2 may look like on a real pedigree. Obviously the other sex offspring not included in the relevant rule might be affected, but for simplicity sake i made them non-affected in the examples. This is not intended to be used to learn the nuances of genetics, this is to get points right on test day.


TL:DR - just memorize rule #1 and rule #2 if you want to get all X-linked pedigrees correct.

Damn you made something thats usually really complex to understand, easy thanks man !

Rule no.1=all daughters and sons effected from effected mother (mitochondrial)
Rule no.2=Generations skipped;Recessive pattern
Generation not skipped;Dominant pattern
Rule no.3=effected daughters from effected father and no male to male;x-linked dominant otherwise autosomal dominant
Rule no.4=effected sons from uneffected parents;x-linked recessive otherwise autosomal recessive

Excellent and I think the most easiest way to overcome in understanding x linked diseases

I usually think Dad-Daughter->Dominant (DDD). Thank you for the video.

I did not get it in class and i expected it to be like super hard but it’s literally so easy! Thank u

[tonimahan]

Thank you so much ! Exam in two hours I needed this

[abdulrahmanenayeh]

you made a mistake making the pedigree in the middle at minute 4:03 the sons should be dominant X and recessive X not both dominant. But other wise this is great. Thanks

[depression]

[KhardhyBhanks]

since most of the people nowadays perform ASMR video, It is helpful to use it in MB exam:

ASMR;

Son
Mother
Recessive
