1. There are 3 alleles controlling the ABO blood types. IA and
IB are codominant genes so that the combination IAIB produces
the AB blood type. The third allele, (i) is recessive to the other
two alleles. Show your work for each cross.
Indicate which of these parents could produce the given child.
The first one is provided with answers as an example.

blood type may yield different results.)

father is an albino marries an albino man whose parents are
normal. They have three children, two normal and one albino.

Describe a situation where you need to teach an adult or child a
task that needs to be generalized. Some examples might include

16. teaching a toddler to get dressed, a child to read, or an adult to
send an email. Discuss the elements of generalization training
that will be most important in developing the transfer of
learning to new situations.
