It is difficult to determine the sex of very young chickens, but it is easy to tell, by visual
observation, whether the feathers are "barred." The barred pattern is inherited as a
sex-linked dominant trait. This trait is used regularly by chicken breeders who receive
orders for only male or female chicks, and must be able to deliver the appropriate sex of
very young birds. Determine whether the male and female parents should be taken from
normal or barred true-breeding lines in order for the sex of all chicks to be determined at
the time of hatching. Show the Punnett square for the mating you select, to confirm that
the desired phenotypes result.
