Double-trouble: Tiger gives birth to twin cubs - one yellow and one white

Cubs Jinliang and Yinshuai aren't any ordinary twins. Workers at Tianjin Zoo, China were shocked when the pair were born - because they arrived into the world in completely different colours - yellow and white.
The furry feline's mother Meimei was a mixed blood tiger - and it seems each of her offspring has unusually inherited each of her different colours.
The yellow cub has the hue of a common Bengali tiger - but the animal genetics would normally make the birth of his white brother virtually impossible. The twins were born on May 31st.
The Bengali tiger is the most common tiger subspecies and is the national animal of both Bangladesh and India.
The cubs difference in appearance is due to an extremely rare gene defect. LINK
