    Male maker x female banana?
    What normally happens if you breed a male maker banana to a female banana? Does the banana offspring still come out as males or does it normalize the ratio because of the genetics from the female?

    The female will throw a normal sex ratio but ,iirc, any males produced will be female makers.

    Short answer:
    The result is expected to be banana females, normal females, super banana males and male maker banana males in approximately equal numbers. Rarely a super banana female, normal male or female maker banana male shows up.


    Long answer:
    Xb = banana gene on X choromosome
    X+ = normal gene on X choromosome
    Yb = banana gene on Y choromosome
    Y+ = normal gene on Y choromosome


    Xb/Xb = super banana female
    Xb/X+ = banana female
    X+/X+ = normal female

    Xb/Yb = super banana male
    Xb/Y+ = banana male (female maker)
    X+/Yb = banana male (male maker)
    X+/Y+ = normal male

    Most of the time, a banana male (male maker) (X+/Yb) x banana female (Xb/X+) produces
    1/4 Xb/X+ = banana female
    1/4 X+/X+ = normal female
    1/4 Xb/Yb = super banana male
    1/4 X+/Yb = banana male (male maker)
    In the above list, the egg's chromosome is first, and the sperm's chromosome is second.

    Less than 10 percent of the sperm and eggs have a crossover. In sperm, the banana gene on the Y chromosome has switched to the X chromosome, and the normal gene on the X chromosome has switched to the Y chromosome. In eggs, there is no difference between crossovers and non-crossovers.

    Results from crossovers:
    1/4 Xb/Xb = super banana female
    1/4 X+/Xb = banana female
    1/4 Xb/Y+ = banana male (female maker)
    1/4 X+/Y+ = normal male
    In the above list, the egg's chromosome is first, and the sperm's chromosome is second.
