What it means, when a gene is an autosomal recessive
... When a gene is referred to as an "autosomal recessive," it means: (a) That the gene is NOT on the X or Y chromosome, but one of the "normal" ones. This is important in that "X-linked" diseases inherit in a different pattern than autosomal ones. (b) That the gene must be present in TWO COPIES for dis ...
