Computer Simulations Are Sometimes Used to Demonstrate the Outcome of Monohybrid

question 41

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.
