Labrador retrievers have the possible coat colors of black, brown, or golden. Two genes are involved in the color. A gives black and is dominant to a. When aa occurs, the color is determined by B/b genes. B is dominant for brown, but only if no A is present. The combination bb is epistatic to the A locus and gives golden regardless of the A/a alleles. Indicate the color of the parents given. Then work out the crosses with Punnett...
A series of hamster crosses are performed to get an insight into the mode of inheritance of three coat colors
A series of hamster crosses are performed to get an insight into the mode of inheritance of three coat colors: plain brown, plain beige, and patchy brown. Note that not all the parents were pure-breeding. Propose a mode of inheritance for coat color in hamsters, using symbols of your own choosing to identify genes and alleles.

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...

31. In rabbits, an allelic series helps to determine coat color: C (full color), cch (chinchilla, gray color), ch (Himalayan, white with black extremities), and c (albino, all white). The C allele is dominant over all others, cch is dominant over ch and c, ch is dominant over c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C >ch >c"> c. The rabbits in the list on the following page are crossed...
