If I breed a dark color betta female with a dark color betta male

Question

If I breed a dark color betta female with a dark color betta male

will I get all dark color offsprings, or is it possible for me to get some light colors too?

Answer 1

depends on what genes they both are carrying but is it possible yes  

Answer 2

It is possible that you can get dark colors, light colors, and any mixture of the above.  Most bettas don't "breed true" unless they come from a breeder and have bred true for several generations.  If you bought these bettas from a pet store, then you could get any variety of offspring.  Here is a webpage on betta genetics if you want to learn more:  http://www.bettas-jimsonnier.com/genetic...
