Chinese scientists announced that they have achieved a breakthrough in yak cloning.
With ten cloned calves all naturally delivered in southwest China's Zizang Autonomous Region.
These calves, consisting of three black yaks and seven white ones, were born from March 25th to April 5th.
At a yak breeding and research base in Zizang's Dangzhong County,
all meeting expected standards and steadily gaining weight.
Fang Sheng Guo who led the research team from Zhejiang University,
said this shows the technology moved from a one-time success to a stable mass-scale application.
The mass births came after the first cloned yak was born in July 2025, which has grown healthily.
And weighs about 183 kilograms now, yaks are endemic to the Qinghai Zizang Plateau,
serving as both a key livelihood asset for local herding communities and an integral component
of the plateau's ecosystem, unlike ordinary cattle cloning.
Yaks have developed unique cellular mechanisms to adapt to the plateau's low oxygen and strong ultraviolet radiation.
The joint project by researchers from the Regional Plateau Institute of Biology,
the Dangjiang County Government, and Zhejiang University.
Used whole genome selection and somatic cell cloning technologies to produce the cloned yaks.
