"Crossing this(Ruthven's x alterna) back to a pure Alterna you (could) get these results:
aaaaaaaa = pure alterna"

Or assuming 36 chromosones as typical for colubrids what are the odds of Ra(x36) aa(x36) = aa(x36)?



And when disscussing such F1 parental backcrosses in general shouldn't the simple 75%/25% be used unless you are discussing specific amimals that have been tested as to exact genetics?
