    Bumblebee question
    Since a bumblebee is a combination of two codom traits, what would be the results if you crossed it with a normal? If anyone knows...

    i figured that so it would be in the 9:3:3:1 ratio?

    The theoretical ratio if you crossed a Bumblebee (SsPp) to a Normal (sspp) would be 1:1:1:1.

    The actual ratio might be something different though. Actual Ratios approach (converge towards) theoretical ratios with large numbers. (The law of large numbers) That's why Mendel's choice of the Pea Plant as a model organism was good since he could get offspring numbers in the hundreds rather than single digits.


    The 9:3:3:1 ratio occurs when you cross two double hets recessive for the traits of interest.


    For example an albino and a pied……

    Instead of thinking of it as a ratios with organisms that dont have tons of offspring at once it is better to think of it as the chance of each egg being something. i.e. You have 25% chance for each egg to be a Bumblebee.

    Hope that helps.
