yes and no
If the banana is a male and his father was banana 99% of banana produced will be male with 1% female
if the banana is male and his mother was banana then 99% of banana produced will be female with 1% male
if the banana is female you get a 50% male and 50% female. and the male banana out of her will be in the 99% female makers
all non banana offspring are usually (but not always) the opposite sex of what ever the banana makes
