Question

Chicken can have different types of feathers. Frizzled feathers curl toward 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?

Answer 1

F=Frizzled
f=straight

ff x ff 


   f    f 
f  ff   ff
f  ff   ff

therefore the percentage is 0/4 so the chance of the offspring that will have frizzled feathers is 0%.
