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.

It is highly unlikely to have exactly 100 offspring, an even split between males and females, and a precise 3-to-1 phenotypic ratio in real life. In real life, there may be variations in the number of offspring and sex ratios, which may result in slight deviations from the expected phenotypic ratios.
