Computer simulations are sometimes used to demonstrate the outcome of monohybrid fruit fly crosses,where a student can run generation after generation of fruit flies with 100 offspring produced each generation,half male and half female,and a 3-to-1 phenotype ratio (or 75 to 25)in the F₁ generation.Compared with real genetics results, A)rarely would exactly 100 fly offspring be produced or survive. B)an exact balance between males and females would be rare. C)a precise 3-to-1 ratio would be uncommon. D)All of the choices are true.

In real genetics, exact numbers like 100 offspring, a perfect male-to-female ratio, and a precise 3-to-1 phenotype ratio are uncommon due to natural variations and environmental factors.
