Part 2 Procedure:
The female monster (described in Table 1 your monster) is married to a male monster (see
Table 2 below) and they plan to have baby monsters. They are interested in finding out the
probabilities of which traits their offspring will have.
1. Fill in the missing genetic information in the table for the male. (do this in your journal)

2. Create Punnett squares (in your journal) to predict what traits would result from a
cross between the two monsters for (Eyes, Tail, Feet, Ears, Claws) and answer a-e.
(You should cross your monster from the other day or the monster in Table 1 with the
monster from Table 2 above).
a. Eyes – What percent of offspring will have only one eye? _________
b. Tail – What percent of offspring will have a tail? _________
c. Feet – What percent of offspring will have three toes? _________
d. Ears – What percent of offspring will have ears? _________
e. Claws – What percent of offspring will have long claws? _________
