克隆（Clne）是指生物体通过体细胞进行的无性繁殖，以及由无性繁殖形成的基因型完全相同的后代个体组成的种群。通常是利用生物技术由无性生殖产生与原个体基因完全相同的个体或种群。

1. What was the first clned mammal? What happened t her?
It was a sheep named Dlly in 1996.At first, Dlly grew nrmally. But later she develped an illness that is mre nrmally fund in much lder animals. She lived fr six and a half years, nly half the life f the sheep frm which she was clned.

After Dlly, scientists have clned mre than 20 mammal species, including camels, cattle, deer, dgs, gats, and mice.

In January 2018, Chinese scientists annunced the clning f tw lng-tailed mnkeys, Zhng Zhng and Hua Hua. They were the first-ever primates t have been clned! Clning primates is much harder and ding s with nn-reprductive cells was even mre cmplicated.
