A male who has an allele for the HD (Huntington's disease) mates with a woman who is phenotypically normal. What proportion of their children will carry the trait (meaning have it although not show the symptoms at any time in their life) and what proportion of their children will really have the disease all along with the trait?
Some families are well-known for having lots of children of one sex or another. For ex one family might 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? Supposing no other biological description exists? (I know there are descriptions to having all one sex of children, just to note, however we are not considering that here).
