A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
At night, humans can use flashlights to spot animals that possess tapetum lucida by causing a phenomenon called eye shine.. Eye shine is the iridescent glow observed in animals when light is shone into their eyes, which floods the eye with light that is then reflected by the tapetum lucidum.
The job of the tapetum lucidum is to improve your dogs vision in dim light, and it does this by reflecting light back to the retina. The more light the retina receives the more information it has to work with to translate that light into images (thatâs a very simplistic version of how our eyes work!).anuary 1, 2010 at 8:44 am. I searched to find this subject because I have been around hundreds of dogs throughout my life and I have never seen their eyes glow anything other than green or red. I have just recently adopted a pure white pitbull and her eyes glow the most beautiful bright blue.
