i has a detached earlobes inherited from my parents.这句话语法对不对

I 应该用 have,
再问： 问题是：what traits have you inherited from your parents? 为什么you前面用的是have 而不是has? I必须用have吗？
再答： I, you ,they 和众数就用have ，I have which are inherited from my parents. He , She ,it 或 名字如Susan....单数等等就用has。
再问： i have a detached earlobes inherited from my parents. 这样就对了吗？？
再答： 应该可以。
