Chickens have different types of feathers. Frizzled feathers curl towards a chicken's head. Assume that feather type is determined by a single gene and that the allele for frizzled feathers is dominant over the allele for straight feathers. In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have frizzled feathers?
0%
25%
50%
100%

A roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan steer mate together?
4: Orange and White
1: Orange : 1 White
2 Orange: 2 Orange and White: 0 White
1: Orange: 2 Orange and White: 1 White
In rabbits, the color of the fur is determined by Full Color > Gray > Himalayan > Albino. This is an example of:
dominance hierarchy
codominance
incomplete dominance
epistasis
B = Black, b = Chocolate. Some labs inherit black or brown fur alleles but have light fur. This graphic shows an example of...
Codominance
Epistasis
Mendelian Dominance
Polygenic inheritance
B = Black, b = Chocolate. ee = no pigment
What is the phenotype of a dog that is Bbee?
Black
Chocolate
Yellow Lab (brown skin)
White lab (black skin)
B = Black, b = Chocolate. ee = no pigment
What is the phenotype of a dog that is bbEe?
Black
Chocolate
Yellow Lab (brown skin)
White lab (black skin)
