Not every gene is dom/rec. You don’t get one or the other. If one parent has a recessive, the other may have a recessive also. Therefore, it could be a 50/50 shot of you getting either or. Maybe your siblings all got one recessive and you got another.

In order to inherit a recessive trait, an individual must receive two copies of the recessive gene, one from each parent. In the case where only one parent has a recessive gene, there is a 50% chance that the individual will inherit the gene from that parent and therefore have the trait. This is because each parent contributes one gene to each offspring during reproduction, and whether or not the individual inherits a particular gene is determined randomly.
