What is Weavers syndrome?

Weaver syndrome is a rare genetic condition that causes bone overgrowth. People with Weaver syndrome are usually very tall and may have distinct facial features, such as wide set eyes.

You can have more features that are dominant from one source than the other, but both sets genes will still alter the features of your vocal cords so you might get as much as 70% or 80% similarity to the ancestors with the more dominant genes but genes from the other parent will still affect how your voice sounds to ...
