To check the expected results, lets make a punnet square:

Be Be be be

BE BBEe BBEe BbEe BbEe

Be BBee BBee BbEe BbEe

bE BbEe BbEe bbEe bbEe

be Bbee Bbee bbee bbee

10:6 is the expected phenotype of the offsprings. There is a 63% chance that the offsprings will be black labrador and there is a 37% chance that the offsprings will be yellow labrador.
