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 to real genetics results,which of the following is NOT true?

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) It is usually possible to have exactly 100 offspring,half male and half female,and a 3-to-1 phenotypic outcome in real life.
E) Ratios and outcomes will not be exact but will be very close to the expected numbers.
