There is a dwarfing allele (D₂) in White Leghorn chickens, which reduces body size from 5 lbs (D₁D₁, D₂D₂) to 3 lbs (D₂D₂) on average. There is also a reduction in the annual egg production from 290 eggs/year (D₁D₁), to 280 eggs/year (D₁D₂) to 220 eggs/year (D₂D₂). Egg size also goes down a bit too, but not enough to affect egg value. The frequency (q) of the dwarf gene D2 is 9pts a) Complete the table below for both body weight and annual egg production for your flock.
