This is an eight locus problem. It is a logic problem that requires multiplying fractions. A bright 13 year old could solve it if the right method is explained.what will I get If I breed my albino pastel 100% het clown 66% het caramel to my mojave cinnamon 50% het hypo and vpi axanthic together????
1. Break down the problem into 8 single locus problems.
a. albino x normal --> 1/1 het albino
b. pastel x normal --> 1/2 pastel, 1/2 normal
c. het clown x normal --> 1/2 het clown, 1/2 normal. AKA 50% probability het clown.
d. 66% het caramel x normal --> Disregard as het caramel cannot be distinguished from normal. And all may be normals.
e. normal x mojave --> 1/2 mojave, 1/2 normal
f. normal x cinnamon --> 1/2 cinnamon, 1/2 normal
g. normal x 50% het hypo --> Disregard as het hypo cannot be distinguished from normal. And all may be normals.
h. normal x 50% het vpi axanthic --> Disregard as het vpi axanthic cannot be distinguished from normal. And all may be normals.
2. Make a branching system. All babies are either pastel or normal (not pastel). Each of those 2 branches is either mojave or normal (not mojave), making 4 branches. Each of those four branches is either cinnamon or normal (not cinnamon), making 8 branches.
---------------------------1/2 cinnamon
--------------1/2 mojave <
---------------------------1/2 normal
1/2 pastel <
---------------------------1/2 cinnamon
--------------1/2 normal <
---------------------------1/2 normal
---------------------------1/2 cinnamon
--------------1/2 mojave <
---------------------------1/2 normal
1/2 normal <
---------------------------1/2 cinnamon
--------------1/2 normal <
---------------------------1/2 normal
3. Follow each branch from left to right and multiply the fractions to get the final probability.
1/2 pastel - 1/2 mojave - 1/2 cinnamon = 1/8 pastel mojave cinnamon
1/2 pastel - 1/2 mojave - 1/2 normal = 1/8 pastel mojave
1/2 pastel - 1/2 normal - 1/2 cinnamon = 1/8 pastel cinnamon
1/2 pastel - 1/2 normal - 1/2 normal = 1/8 pastel
1/2 normal - 1/2 mojave - 1/2 cinnamon = 1/8 mojave cinnamon
1/2 normal - 1/2 mojave - 1/2 normal = 1/8 mojave
1/2 normal - 1/2 normal - 1/2 cinnamon = 1/8 cinnamon
1/2 normal - 1/2 normal - 1/2 normal = 1/8 normal
And all babies are het albino and 50% probability het clown
Fractions are the probability of a given result for each egg, not per clutch.
