Converting Genotype into Phenotype:
What do the following individuals look like?
1- If A is dominant to a, what do "AA" "Aa" and "aa" look like?
2- If B and b are codominant, what do "BB" "Bb" and "bb" look like?
3- If c is recessive to C, what do "CC" "Cc" and "cc" look like?
4- If D is dominant to both d1 and d2, and d1 and d2 are codominant to each other, what do "DD" "Dd1" "Dd2" "d1d1" "d2d2" and "d1d2" look like?
5- BB x Bb
6- bb x Bb
7- bb x bb
8- Bb x Bb
9- BB x bb
Combine two results. Use FOIL on each trait, then combine with a grid.
10- CCDD x CcDD
11- ccDd x ccdd
12- CCdd x ccDD
13- CcDd x CcDd
14- Ccdd x CcDd
Use FOIL for each trait to get all three results. Combine two into a grid, then add the third.
15- aabbcc x AaBbCc
16- aaBbCc x AabbCc
17- AaBbCc x aaBbcc
18- AaBbCc x AaBbCc
Use the shortcut shown in Step 9 by multiplying "odds per locus" to find the desired outcome.
19- When crossing AaBbCcDdee x aaBbccDdEe, what are the odds of getting aabbccddee?
20- When crossing AaBbCcDdEe X AaBbCcDdEe, what are the odds of getting aabbCcddee?
21- When crossing AaBbCcDdEe X AaBbCcDdEe, assuming "e" is recessive, what are the odds of getting offspring showing recessive traits a, b, c, and d, but not e?
