The mystery has been solved. The baby giant panda born at the National Zoo on August 24th is a girl.
Research scientist Jesus Maldonado said on Thursday, "We have another girl in our family. We conducted genetic analysis...and we are proud to announce that the sire is Tian Tain."
The mother of the cub is a panda named Mei Xiang [pr: May Shong]. Zoo officials had to conduct the genetic analysis because the panda cub was conceived by artificial insemination in late March using the semen from Washington panda Tian Tian and Gao Gao from San Diego.
The baby panda has a "a fat little belly," is "very active" and is beginning to get some fuzz and markings. The cub still doesn't have a name, since the zoo is following the Chinese tradition of waiting 100 days after birth to pick one.
