With independent assortment, the ratio of genotypes in the F2 generation of a cross between true-breeding strains (AA bb * aa BB) can be described as 1:2:1:2:4:2:1:2:1. To what genotype does the "4" in the ratio refer?

    AaBb

    Explanation:

    Cross between true breeding strains

    Parents: AAbb x aaBB

    Gametes: Ab aB

    The F1 is homogeneous: AaBb.

    To obtain the F2 generation we must do a cross between 2 F1 individuals: AaBb x AaBb

    Their genotypes are the same, so they both will produce the same type of gametes: AB, Ab, aB and ab.

    If you do a Punnett Square, you can check the ratio of genotypes of the F2, and that the "4" refers to AaBb.
