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.
Chrysopelea, more commonly known as the flying snake or gliding snake, is a genus that belongs to the family Colubridae. 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.
Why are flying squirrels called flying squirrels? This is because they can glide through the air as a means of moving  from location to another and so it would be natural to ascribe to  them this characteristic of 'flying'.â¦    Flying squirrels' origins go back 33 to 55 million years. How they  came upon their name isn't clear, but the anatomy of this animal  gives it the ability to soar.
