Computer Simulations Are Sometimes Used to Demonstrate the Outcome of Monohybrid

Multiple Choice

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.
