Question

In 3 or more complete sentences, please discuss how the use of that DNA inheritance patterns could be helpful in forensic science. Include an example of one of the patterns discussed in the lesson (dominant, recessive, codominant, sex-linked, polygenic, multiple alleles).

Answer 1

When someone claims to be children of someone, inheritance pattern can be used to prove whether it is possible or not. Dominant trait (like cleft chin) will always be expressed so it cannot appear from a parent without the trait.
If the father and mother don't have a cleft chin, it would be impossible to have a child with a cleft chin. That way, the claim can be considered as impossible/false.
