I really want to tell you about my friend, one of my best friend is Tuan. We were classmate during our five years at Da Nang University of Technology. He was a good student of my class. He has black hair and bright eyes and is very good – looking. Tuan and I had many things in common, especially, our hobbies. We both traveling, billiard, table tennis, reading book and singing.
He has a kind heart and is easy to get on with everybody. The deeper our mutual understanding becomes the more we feel closely attached to each other. We are the best pupils in our class. Tuan is always at the top. He is good at every subject, but he never shows pride in his abilities and always tries to learn harder.
Tuan’s family is not rich. His parents are farmers. He often spends most of his free time doing useful things to help his parents. I Tuan very much because of his honesty and straight forwardness. He is always ready to help his weak friends in their study; as a result, lots of friends, thanks to his whole-hearted help, have become good ones.

Để sinh ra con có chung một kiểu gen và kiểu hình về nhóm máu thì vợ và chồng cũng phải cùng nhóm máu.
Có 3 KG đồng hợp là IAIA, IBIB, IOIO
Tỉ lệ KG IAIA là 0.16, IBIB là 0.09 và IOIO là 0.09
Xác suất tìm thấy các cặp vợ chồng mà mỗi cặp vợ chồng đều sinh ra các con có chung kiểu gen và kiểu hình là
0.16 x 0.16 x 2 + 0.09 x 0.09 x 2 + 0.09 x 0.09 x 2 + 0.16 x 0.09 x 2 + 0.16 x 0.09 x 2 + 0.09 x 0.09 x 2 = 0.1574 (hay 15.74%)
Vì vai trò của bố mẹ là khác nhau nên phải nhân 2 ở mỗi xác suất kiểu gen có được. Ở đáp án bài trên chắc tác giả cho vai trò của bố mẹ là như nhau.
