Ok.
Assume first female is an f1
Female Bananas produce male and female offspring in apparently normal ratios.
Male (f1) bananas produced from female(f1) bananas will produce mostly male Bananas. We can assume it to be 99% of the time. All normal or non Banana offspring are regular male/female ratios.
If a female (f2) is produced from a "male maker" (f1) Banana, She will produce males and females at normal ratios, but any male (f2) Banana will now make females and males at in normal ratios.
So it is a sex linked recessive gene which does happen and is illustrated and explained in the previous links I posted for you.
Why is this so hard for you to understand?
