Question

If individual 1 in generation had the same phenotype as his wife ,what are the chances that There children would have rickets

Answer 1

By taking a glance at the pedigree we can see that rickets transmission is not autosomal but instead it is x linked recessive.
Without wasting time look at the no of offspring of 1 that is 4 since two out of four have rickets then the chances of having rickets by method of probability is 1/2
