It's a girl!
The Smithsonian's National Zoo announced on Thursday that its two-week-old giant panda cub is female and her father is National Zoo panda Tian Tian (tee-YEN tee-YEN).
Panda mother Mei Xiang (may-SHONG) was artificially inseminated with sperm from Tian Tian, as well as a panda named Gao Gao at the San Diego Zoo. It takes time to determine a cub's gender, and a DNA sample was collected to determine the paternity of the cub born on August 23.
A second, stillborn cub delivered a day later was also female and also sired by Tian Tian, officials said. The cubs were fraternal twins.
The surviving panda cub has been described as healthy and active. Zookeepers conducted a 10-minute physical examination days after it was born. Veterinarians said the cub had a steady heartbeat and appeared to be digesting its food.

China owns the pandas at the Smithsonian's National Zoo. The cub is expected to stay with her mother for a little over two years until she is weaned. Mei Xiang's only other surviving cub, a male named Tai Shan, was born in 2005 and was returned to China in 2010.
Mei Xiang gave birth to a cub last year after several years of failed breeding, but the cub died after six days. Its lungs hadn't fully developed and likely weren't sending enough oxygen to its liver.
