A male who has an allele for HD (Huntingtons Disease) mates with a woman who is phenotypically normal. What proportion of thier children will carry the trait (meaning have it but not show the symptons at any time in their life) and what proportion of their children will actually have the disease along with the trait?

Some families are known for having lots of children of one sex or another. For instance one famnily may have 10 children all boys! What are the odds of that? If they have an 11th child what will be the odds of having a girl? Assuming no other biological explanation exists? ( I know there are explanations to having all one sex of children, just to note, but we are not considering that here)
