Question

if a claimant has a genotype of Ww can they be a possible heir, why or why not

Answer 1

I think you need to give more information. What gene trait are you referring to? and what are the genotypes of the parents? Is the trait recessive/dominant?

Answer 2

We really need more information.
genotype Ww will look like WW
Both Ww and WW are phenotype of W, only ww will look different
