Genetics question

In chickens, one pair of co-dominant alleles affects the type of feathers forms, in the homozygous condition FF produces chickens with “frizzled” feathers, while homozygous FN chickens have normal feathers. The heterozygous chickens have feathers which are curled. A curled hen and a curled rooster have a bunch of chicks; Determine the phenotype ratio of chicks with curled feathers and chicks without curled feathers. Show all work! (2T/2C) Of the chicks that don’t have curled feathers, which genotype (s) would be referred to as “pure” breeding? (pure-breds) (1T) A What chicken breeder wants to build a “herd” of curled feather chickens. Which type of chickens should he allow to mate in order to produce chicks that ALL have curled feathers?
