The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain.

- In a species of bird, feather colour is determined by a single, non-autosomal gene that shows complete penetration. A red-feathered female mates with a blue-feathered male, and all the F1 males are blue-feathered and the F1 females are red-feathered. When the F1 individuals are crossed, all the F2 males are again blue-feathered and the F1 females are again red- feathered. Provide the genotype of the F2 males and females.
