    Hi all- Sort of. The calculation involves (n)(n+1)/2 "parts". Paste the following formula in C2 and copy down. Then sum Column C (not shown).

    =B2*SUM(B$2:B2)

    Re: how to calculate the probability to be homozygous?

    I am nor sure about your answers ...
    I added in a (very) small sample what my data look like when I do it manually (which is impossible if you have more than 300 frequencies to multiply )

    In blue are the formula I used.

    I hope this will help!
