Quizplus · Accepted Answer

The Punnett square shows that both parents have one copy of the allele that causes the disorder and one copy of the normal allele. This suggests that the disorder is autosomal, meaning that the gene that causes the disorder is found on one of the non-sex chromosomes. If the disorder were sex-linked, it would be more likely for males to be affected since they only have one X chromosome. Additionally, if the disorder were incompletely dominant, we would expect to see some offspring with intermediate phenotypes rather than just affected or unaffected. Finally, if the disorder were the result of the linkage of A and B genes, we would expect to see a different pattern of inheritance.
