thank you for this amazing explanation

Soo nice Analysis sir

[@amirulfaez8437]

What if observed phenotypic count for blood type O is zero?

[@GeneticsLessons]

Is it just general question or relates to the video?

thank you so much

You're welcome!

How can I calculate the fraction of the population with blood type A. A^2+2AO or just A^2?

[@GeneticsLessons]

No, here is the formula F=(A+B+O)^2

[@kevingil1356]

@@GeneticsLessons TY for answering me. But if the question were about the fraction of A?

[@GeneticsLessons]

F=(a+b+o)^2 = (a+b+o)*(a+b+o) F=(a+b+o)^2 = a^2 + a*b + a*o + b*a + b^2 + b*o + o*a + o*b + o^2

[@GeneticsLessons]

So, a^2+2ao/a^2 + a*b + a*o + b*a + b^2 + b*o + o*a + o*b + o^2

[@GeneticsLessons]

Or just a^2+2ao cause all the frequencies combined are 100%

You sound like Gru from the despicable me movies, I love it

[@GeneticsLessons]

Haha, second time I'm told so...
