Understanding Erminette Chicken Genetics
Erminette Chickens (BW) Genetics
Erminette chickens (BW) display codominance. Black is dominance. White is dominant. Erminette chickens are speckled with black and white feathers.
Phenotypic Ratio of Offspring
What is the phenotypic ratio of the offspring if two erminette chickens are crossed?
Answer:
1 BB: 2BW: 1WW
Explanation:
The probability of getting a black chicken is 1/4, that of black-white is 1/2 and that of a white chicken is 1/4. In codominance, there is intermediate expression in the phenotype.
B W
B BB BW
W BW WW
The phenotypic ratio is 1 black: 2 black-white: 1 white
Further Exploration
Have you ever seen an erminette chicken in person? How fascinating is it to witness the genetic traits of these chickens being expressed through their unique coloration!
Erminette chickens (BW) display codominance. Black is dominance. White is dominant. Erminette chickens are speckled with black and white feathers. What is the phenotypic ratio of the offspring if two erminette chickens are crossed? Answer: 1 black 2 erminette 1 white Explanation: The phenotypic ratio of the offspring when two erminette chickens are crossed is 1 black: 2 erminette: 1 white. This ratio reflects the codominant expression of black and white traits in erminette chickens' feathers, resulting in their distinctive speckled appearance.
