A couple in Illinois is celebrating the birth of their rare biracial twins.
Kalani Dean and Jarani Dean were born on April 23, 2016, according to KHQA. Their mother, Whitney Meyer, is caucasian, and their father Tomas Dean is African American.
To announce the twin biracial girls turning nine months old, Whitney posted a photo to the KHQA’s Facebook page.
“Local Quincy II Biracial Twins!! One is white and one is mix! Really odd and neat!! Just wanted to share with our community!!!” Whitney captioned the photo.
The girls are fraternal twins, meaning each was born from separate eggs that were fertilized by two different sperm cells.
For a biracial couple expecting twins, there is about a one in 500 chance that the children will have different skin colors, Dr. Jim Wilson, a population geneticist at the University of Edinburgh, told the BBC.
The rarity of biracial twins made it hard for Whitney to believe it had happened with her daughters.
“At first when they were born, I wanted to believe it but it’s so rare I didn’t think it’d happen to my twins! But sure enough they’re biracial twins!” she told KHQA.
The twin girls not only look different, they also act differently. Kalani has lots of energy and is crawling, while Jarani loves to eat and has yet to find the desire to crawl.
Whitney shares pictures of the girls on Facebook, and wants people to know all about them.
“Like/share us please!! We’re chromosome twins. Kalani(on left) is light with blue eyes and Jarani(on right) is the darker one with brown eyes. This is rare but so awesome to share!! How many likes can we get?” she wrote with a picture of the girls in November.
The post received more than 2,000 reactions and was shared over 200 times.
It also prompted another mother of biracial twins to share a photo.
“My twins are unique that way too,” Jill McMillan commented with a picture of her children.
