FOLD and LABEL your paper as shown here so you’re ready to move on when the bell rings!• Fold your paper in half twice, so you

have four boxes.• Label the boxes 1-4 EXACTLY like mine

(3 & 4 are supposed to be upside down!).

1 24 3

Now let’s make a booklet…•Cut along the fold line between

#1 and #4 – be sure to STOP when you get to the center!!

• Fold the half with 3 & 4 back, so you are looking at 1 & 2.

• Fold #1 to the right. Write GENETICS VOCABULARY on the back of that page.

Now let’s make a booklet…• Turn the whole thing over, and

fold #4 to the left. Turn your booklet over.• You should now be able to flip

your pages and see them in order, 1-2-3-4

What are the vocabulary words?•On page 1, write the following words (leave SPACE to write definitions!):•DOMINANT•RECESSIVE•ALLELE• TRAIT

•On page 3, write the following words (leave SPACE to write definitions!):•HOMOZYGOUS•HETEROZYGOUS•GENOTYPE•PHENOTYPE

You will fill in definitions as you complete today’s activity.

Reebop Chromosomes• On your table, you have a bag with one set of Mom chromosomes

(pink) and one set of Dad chromosomes (blue).• Take out both sets of chromosomes and line up the pink set

according to size.• Now line up the blue set according to size.• Notice the letter on each chromosome?• The capital letter represents DOMINANT.• The lowercase letter represents RECESSIVE.

•With your partner, come up with your best definitions for these two words, and write them on page 1 in your booklet.

Wait…how much of your DNA comes from each

parent?

Reebop Chromosomes• Now, take one pink and one blue chromosome of each size. Line

them up from largest to smallest.• Each letter represents an ALLELE.• Combinations of alleles determine your TRAITS.

•With your partner, come up with your best definitions for these two words, and write them in your booklet.• Look at the combination of letters for each chromosome size.• Both capital or both lowercase represents HOMOZYGOUS.• One capital and one lowercase represents HETEROZYGOUS.

•With your partner, come up with your best definitions for these two words, and write them in your booklet.

Reebop Chromosomes•Look at your Mom & Dad chromosomes TOGETHER (AA, Aa, aa).•This combination represents GENOTYPE.

•With your partner, come up with your best definition for this word, and write it on page 3 in your booklet.

•On the BACK of page 4, write down all of your genotypes (Aa, nn, EE, etc.)

Reebop Chromosomes• Look at the chart below and find the characteristics that applies to

your genotypes. Write them on the back of page 4.

• This represents PHENOTYPE.•With your partner, come up with your best definition for this word,

and write it on page 3 in your booklet.

Characteristic Genotype / phenotype codeantennae AA = 2 antennae Aa = 2 antennae aa = no antennae

body segments BB = 3 body segments Bb = 3 body segments bb = 2 body segmentstail TT = curly tail Tt = curly tail tt = straight tail

nose NN = red nose Nn = red nose nn = yellow noselegs LL = blue legs Ll = blue legs ll = red legs

gender XX = female XY = male eyes EE = 2 eyes Ee = 2 eyes ee = one eye

humps HH = 1 hump Hh = 1 hump hh = 3 humps

Now what?•On page 2 & 4, draw pictures to represent each of the eight vocabulary words.

•When you finish, unfold your booklet. On the blank side, draw your baby Reebop!
