Panda Reveal
ROSHAN PATEL/COURTESY OF SMITHSONIAN NATIONAL ZOO
WHAT’S IN A NAME: Two weeks after his sex was revealed, the cub was named Xiao Qi Ji (shiao-chee-jee), which means “little miracle.”
A GROWING CUB: The young panda gets a checkup from a zookeeper.
This past August, zookeepers welcomed an exciting new addition to the Smithsonian National Zoo in Washington, D.C.: a panda cub. At first, zookeepers didn’t know whether the newborn was a boy or a girl. That’s because young male and female giant pandas look basically identical. To identify the cub’s sex, veterinarians had to test the panda’s DNA. This hereditary material carries information about how an organism looks and functions.
The veterinarians swabbed the cub’s cheek to collect a DNA sample. Once the panda’s DNA was analyzed, the zoo announced, “It’s a boy!” Today, the tiny bundle of joy is doing well, says Laurie Thompson, the zoo’s assistant curator of giant pandas. “His development is right on track.”
Until recently, giant pandas were endangered. Thanks to conservation efforts, their population rebounded. This graph shows panda numbers in the wild and in captivity. Look at the panda population from 1974-1977. Compare this to the total population in 2011-2014. Which is higher?
