Type A is dominant, Type O is recessive. In otherwords your parents could both carry the gene for O, but the A gene they carry overrides it. You just got the O gene from both of them and not the A. It works like this, imagine your mom's genes across the top, and your dad's down the side. They each give you only one.

This flying snake species reaches up to three feet in length and is popular in the European pet trade. Their bodies are black, but covered in rich green scales. Clusters of red, orange, and yellow-coloured scales in the shape of flower petals line the dorsal area from the base of the neck to the tail.
The Anaconda or green anaconda (Eunectes murinus) is the one of biggest snakes in the world. It is a non-venomous boa species from South America. It is the largest, heaviest, and second longest known living snake (behind the reticulated python). The term anaconda usually means this species. This giant snake (which is called the water boa) lives in swampy areas of tropical South America. It spends a lot of time in shallow water, hidden from unsuspecting prey. Anacondas give birth to live young; 20 to 40 baby snakes are born at one time.
