Masalah regarding shares of Aqeeqah

Assalamu alaikum. Respected Mufti Sahab, this is with reference to the question no.11852 dated 25/9/2014. Alhumdulillh you have answered the question and I had my doubts cleared. But here I want to ask one more question. I am a male and I said that I want to do qurbani and also aqeeqah of mine and of my brother. So the question is how will the shares for qurbani and aqeeqah be taken. For my qurbani I have to take One share and for my aqeeqah, do I have to take or calculate one share or two shares in the cow. As I have heard that for a boy(male) either two goats or two shares in a big animal. What is correct. Because the method I have mentioned in question no.11852 there I have written that I am taking one share for my qurbani and one share for my aqeeqah and same for my brother, but I came to know that one has to take two share for aqeeqah for a male.
