As I noted, puddle-shallow - but say person A is heterozygous for the
recessive bad CFTR gene - that's unusual in healthy populations.  Being
homozygous for the dominant is usual.

Under your scenario, one would expect many non-Y children (~25%) for a
dominant gene.

Perhaps the confusion is that I'm assuming a low rate of cross-breeding;
I am by no means saying that this is the principal mode of reproduction
for the Y.
