Minion Madness Genetics
In Minions, having two eyes (E) is dominant, having only one eye (e) is recessive.
1. Two heterozygous minions marry.
a. Tell the genotypes of each parent: ________ & ________
b. What is the percent chance that the offspring will have:
one eye? ___________
two eyes? ________
2. A homozygous dominant minion is married to a heterozygous
minion.
a. Tell the genotypes of each parent: ________ & ________
b. What is the percent chance that the offspring will have:
one eye? ___________
two eyes? ________
3. Two one-eyed minions marry.
a. Tell the genotypes of each parent: ________ & ________
b. What is the percent chance that the offspring will have:
one eye? ___________
two eyes? ________
4. A two-eyed minion (homozygous dominant) is married to a one eyed minion. They have 8
minion children.
a. Tell the genotypes of each parent: ________ & ________
b. How many of those children will have two eyes? ________
5. Marty Minion has two eyes is married to Marsha Minion who has one eye. They have 60
Minion children, 30 of those children have one eye. What are Marty and Marsha's genotypes?
Marty: ___________
Marsha: __________
Height in minions is also controlled by dominant and recessive traits. Tall is dominant (T)
over short (t).
6. Minnie Minion is short and married Melvin Minion who is heterozygous.
a. Tell the genotypes of each parent: ________ & ________
b. What is the percent chance that the offspring will be:
tall? ___________
short? ________
7. Molly Minion is homozygous dominant for height and her husband Milford is heterozygous.
a. Tell the genotypes of each parent: ________ & ________
b. What is the percent chance that the offspring will be:
tall? ___________
short? ________

Having a gap between the two front teeth (G) is a dominant trait over no gap between the teeth (g).
8. A homozygous dominant tall, homozygous dominant gap-tooth minion named Maximillion
marries a heterozygous tall, no gap-tooth minion named Meghan.

a. What are all of the possible genotypes and phenotypes of the children?
9. Two minions, both heterozygous for both traits are married. Out of 16 children, how many of
each genotype and phenotype would you expect?
