In Hoa Binh Province in Vietnam, a couple was stunned to find out that their twin babies have come from the sperm of two different men.
Both the two-year-old babies were sent for DNA testing since their parents saw their difference from each other. The other one has a thick wavy hair and the other one has a thin straight hair.
Based on the results of the tests conducted by Ha Noi Centre for Genetic Analysis and Technology, they revealed that the twins had the same mother but their fathers are different.
This means that the twins are bi-paternal which means they have different fathers but same mother.
This is the first reported case in Vietnam.
