she handed it to an assistant who wrapped it up for her

问题描述:

she handed it to an assistant who wrapped it up for her
请问这句话中的who去掉,改成and 在and 的后面加多the assitant这样的话意思是不是一样的?这句好像是定语从句.

she handed it to an assistant who wrapped it up for her
she handed it to an assistant and the assistant wrapped it up for her
意思完全 一样
