its not 100% that all males are Banana and all females are not. they MOST LIKELY are.. but probably 10-15% of the time a female Banana will pop out.
so you're asking if you can assume that all of the male Albino's in the clutch are Banana also. most likely. are any non Albino Banana's male? usually if you do hit a female Banana one of the others will flip too. but you wont know for sure without breeding it.
