F1 generation, white square and white circle
F2 generation, all offspring are unaffected by trait
F3 generation, all offspring are unaffected by trait
next family:
F1 generation, male is affected (dark square), white circle
F2 generation, 4 females, 3 males. 2 females are affected, 2 black circles
This new F3 generation is the mating of two organisms from the separate families.
One is a white square
One is a black circle
They have 4 offspring, 2 males, 2 females. 1 affected male, 1 affected female
(the 5th child died in infancy)
1.) is the trait dominant or recessive?
2.) is the trait sex linked or not?
