If paternity test says 99.9 percent should the child look somewhat like father?

While a paternity test stating 99.9% probability of paternity is considered highly accurate and significant, it does not guarantee an exact physical resemblance between the child and the father. Physical characteristics, including facial features and overall appearance, are influenced by a complex combination of genetic factors, environmental factors, and random variations in gene expression.

It's important to remember that genetics plays a role in determining physical traits, but it is not the sole determinant. Other factors such as nutrition, growth conditions, and lifestyle can also influence a child's physical development and appearance.

Therefore, even with a paternity test result of 99.9%, it is possible that the child may not have a striking physical resemblance to the father. However, it's worth noting that a DNA test result of this nature strongly supports a biological relationship between the alleged father and the child.
