This condition is called partial albinism, and it's usually inherited but can be caused by other factors.Some birds have just one or two white feathers, while others can be white all over or with big white blotches.ere's a male blackbird that's a great example.

DNA Paternity Testing (sometimes called parentage testing) uses DNA, the biological basis of inheritance, to prove or disprove the relationship between a child and an alleged father. It is based on the fact that we inherit half of our DNA from our fathers and half from our mothers.
A paternity test is a DNA test that is performed to determine if a particular man is the biological father of a particular child.Each of us receives half of our DNA (half of our genes) from our biological mother and the other half from our biological father.he results of a paternity test will be exactly the same for tests performed using buccal swabs or blood (or other samples) because the DNA found in our cheek cells is the same as the DNA found in all of the other cells in our body.
