Can different types of specimens (e.g., blood and buccal swabs) be used in the same case? Yes, DNA tests are the same because the DNA is the identical in all nucleated cells.
Can accurate results be obtained from brothers or related individuals of the alleged father? Yes, the laboratory should be notified of circumstances involving relatives. Although related individuals have similar genetic markers, additional testing can be performed until one man is excluded. What do I need to bring to the sample collection appointment? Legal photo identification (e.g. drivers license, State ID card, passport). Can eye color indicate paternity? No. In humans, there are three genes that are known to control eye color. The expression of these three genes can explain typical patterns of inheritance of brown, green, and blue eye colors. However, they don’t explain everything. Grey, hazel, multiple shades of blue, brown, green, and grey are not explained by these three genes. The molecular basis of these genes is not known; what proteins they produce and how these proteins affect eye color are not known.
