OR Subgenomes Variation among Birds, Sea Turtle and Alligator
由
该图数据计算每种鸟的relative percentage，得到下图：
然后得到:
（1）得到（总体）：
1.The 48 avian genomes lacked OR1/3/7 genes and only 3 members were present in alligator and 1 in sea turtle.
2.In addition, OR12 genes wererelatively rare and thus may contribute relatively less to olfactory sensibility in these species.
(2)单个物种对应subfunction，find 生物学依据，基于此update gene 数据库。
