Banana Hets and Sex Linking

[paulh]

Anything banana would be male. Unless you're lucky enough to hit that 6% or so chance of a female.

Male-maker Banana Het Pied Male mated to Pied Female is expected to produce
~22% Male-maker Banana Pied Male
~22% Male-maker Banana Het Pied Male
~3% Banana Pied Female
~3% Banana Het Pied Female
~22% Pied Female
~22% Het Pied Female
~3% Pied Male
~3% Het Pied Male

The percentages are what I would expect, if that 6% chance of a banana female is correct. What a breeder gets could be considerably different simply from the luck of the draw.

The above works out to 1/2 bananas (mostly male) and 1/2 non-bananas (mostly female). 1/2 of all the babies are expected to be pied and 1/2 non-pied. Female bananas and male non-bananas are the result of the X and Y sex chromosomes swapping the region where the banana gene is located during the process of making the sperm. The pied gene is not in the sex chromosomes. Hope this helps.
