Question

Quizplus · Accepted Answer

Two affected parents can have an affected child (and if the trait is linked to a recessive allele then, most of the time, all the children will be affected). An affected parent can have an unaffected child (this depends on the genotypes of both parents and whether the trait is dominant or recessive). For rare traits, it is assumed (unless shown otherwise) that unrelated individuals who join the family from outside do not carry the trait. Males and females can be differently affected if the gene in question is carried on the sex chromosomes.
