DEF: The passing of traits from
parents to offspring
DEF: The allele that is shown or
expressed even if only one
copy is present.
DEF: The allele that needs two
copies to express the trait.
DEF: The combination of
alleles that an organism has.
This determines what trait the
organism will have.

WW, Ww, and ww are all
examples of the combination of
alleles for a trait, which is
called the___________.
Teacher Key: genotype
The gene for pea seed
color has two different
forms: yellow (Y) and
green (y). These
different forms of a
gene are
called_________.
Teacher Key: alleles
R overpowers r, so it only
needs one copy to
express itself. This means
it is the __________
allele.
Teacher Key: dominant

r gets overpowered by R; it can
only express itself if there are
two copies.
This means it is
the ______ allele.
Teacher Key: recessive

Heredity Vocabulary
Mix and Match
Get your students moving and thinking with this quick yet
effective vocabulary activity.
Teacher preparation:
Print all of the cards on cardstock. If printing in black and white, make a copy of the
vocabulary words on one color of cardstock, the definitions on another, and the
examples on a third color. If printing in color, print all cards on white cardstock.
During class:
Hand out one card to each student. You can easily differentiate by handing harder
cards (such as the more challenging example cards) to the more advanced students.
If the number of students does not divide evenly by three, give one or two students
(depending on the number) one of the “extra” duplicate cards (see the last page of
cards). Be sure to tell those students they will be in a group of four and another
student will have the same card as them.
Explain the activity: Students will move around the room, looking for the word,
definition, and example that fit together. A complete group will have three people
and three cards, each a different color, for the same vocabulary word. Once they
find their group of three (or four if they have an “extra” card) they should move to
the outside of the room so that the rest of the students can continue looking for their
group.
You may need to assist the last few students in finding their group. Many students
also used the word wall cards with definitions (posted on the board) as a resource to
help find the cards that fit with their own. Once students have found their groups,
you can choose to have each group read their words, definitions, and examples or
just the words to the class. If you’d like to continue the activity, students can move
around the room until you give the signal, trade cards with someone next to them,
and find their new group of three. Repeat as many times as desired.
Card Sort Variation
Instead of having students move around the room, make one set of cards for each
pair of students and store them in an envelope. Then students can sort the cards at
their desk by grouping the example, definition, and word cards together for each
word.
