The second possible outcome is where ? = b. This means that some of
our offspring will have golden bud (Bb) or Silver bud (bb).
The first possibility proves that there is no way we can
produce silver bud in the offspring.
The second possibility proves that we will have some golden
bud and some silver bud. Not only that but we can understand clearly
what the frequency will be. Count them!
Bb + Bb = 2Bb
bb + bb = 2bb
2 out of 4 will have golden bud. 2 out of 4 will have silver bud. Half
our offspring will have silver bud! The ration is 50:50.
The second possibility tells us a number of things.
(1) Both parents need at least one b trait each for the silver bud to pass
on if it is a recessive trait.
(2) If any silver bud is produced in the offspring then the mystery
parent B? must be Bb. It can not be BB.
Remember:
Homozygous Dominant: BB = Golden Bud.
Heterozygous: Bb = Golden Bud
