, 8. Dr. Professor has decided to start experimenting with Mexican beans. In his sample of beans,
the allele for “jumping” (J) is dominant to the allele (j) “non-jumping”. In a monohybrid cross, if
the P generation consists of plants that are true breeding then the F2 generation will consist of
organisms that exhibit what ratio of jumping to non-jumping Mexican beans?
a. 3:2
b. 1:2
c. 1:3
d. 3:1
*Yes, I’m aware “jumping” trait in “Mexican Jumping Beans” actually comes from moth larva that are
living inside the beans. But in this case imagine it’s a genetic thing, and that some beans jump and other
beans don’t because of the J allele. Treat the beans like any other plant monohybrid cross.*

b. ¼
c. 1/3
d. ½
10. Referring the pedigree above, what are the odds of couple III-1 and III-2 having an affected
child?
