All modern domesticated pigeons have distinct traits that have been chosen by breeders, including the trait for feathered feet. Although most birds have scaly feet (without feathers), some species, including domesticated pigeons, possess a genetic mutation that allows them to have feathered feet, which is a non-Mendelian trait.

A breeder crosses a homozygous bird with long feathers on the feet (FLFL) with a homozygous bird with scaly feet and no feathers (FNFN), and all of the offspring have feet with unusually short feathers, unlike either parent.

Parent pigeon (F N F N) shows a foot with scaly feet (nonfeathered). Parent pigeon (F L F L) shows a foot fully covered with long feathers. Offspring pigeon (unknown) shows short feathers covering the foot.

Part 1: Based on the information provided, what can you conclude about the pattern of inheritance for the feathered foot gene?
Part 2: Explain to the breeder what happened in this cross. Be sure to include both phenotypes and genotypes in your explanation.
