Feather colour in parakeets is controlled by two genes. Blue colour (B) is dominant over absence of colour (b). Yellow colour (Y) is dominant over absence of colour (y). When a B allele and a Y allele are present, a green parakeet is produced. The probability of obtaining a female or male parakeet is the same as for humans. A green parakeet crossed with a white parakeet produced offspring with four different colour patterns. What is the genotype of the green parakeet?
