Milk Yield-Fat% and Egg Number-Egg Size Correlation

Correct Answer: Negative Correlation

From the notes:

• Milk yield and fat%: Negatively correlated. High-yielding cows have lower fat% due to the dilution effect — more milk produced means each litre contains a lower fat concentration.
• Number of eggs and egg size: Negatively correlated. Hens that produce more eggs tend to lay smaller eggs — a well-known antagonistic relationship in poultry breeding.
