According to the report by the DNA testing centre in Lagos, 27 per cent of paternity tests conducted came back negative, indicating that more than one in four men tested are not the biological fathers of the children in question.
The report noted a significant increase in DNA tests for immigration purposes, growing more than any other test type, as more Nigerians seek opportunities abroad.
The trend also suggested that a growing number of parents with dual citizenship were processing paperwork for their children’s emigration.
On regional dominance, the report showed that Lagos dominated, a reflection of economic disparity.
An overwhelming 73.1 per cent of all DNA tests were conducted in Lagos, with 67.5 per cent done on the Mainland and 32.5 per cent on the Island.
The report also showed that the Yoruba ethnic group accounted for 53 per cent of tests, followed by Igbo at 31.3 per cent, with Hausa at only 1.20 per cent.
