2. Task#2
Q: What have you inherited?
On your flap (above the question) write
the following:
A: traits
Heredity: the passing on of
traits from parents to offspring
*traits are different forms of a
characteristic and are
controlled by genes
Task#3
How Traits are Inherited
On your flap (above the title) write the
following:
Genes: control traits, made of
DNA (located on
chromosomes)
Alleles: different forms a gene
may have for a trait
Example – Hair line
(Widow’s Peak or Straight)

3. Task#4
The Father of Genetics
On your flap (above the title) write the
following:
Gegor Mendel
(an Austrian monk)
1856 : Experimented with garden
peas to learn about patterns of
inheritance (studied 7
characteristics/traits)
Genetics: the study of how traits are
inherited through the action of
alleles.
Task#5-2
Dominant
On your flap (above the title) write the
following:
Dominant: the allele that
masks the other allele that it’s
paired with. Allele is
represented by a capital letter.
*Always shows up
Example:
Plant Height – Tall (T)

4. Task#5-1
Cut this flap in half.
(just like we did with the photosynthesis
C.R. foldable)
Dominant vs. Recessive
Task#5-3
Recessive
On your flap (above the title) write the
following:
Recessive: the allele that is
masked or covered up by a
dominant allele unless paired
with another recessive allele.
Allele is represented by a lower
case letter.
Example:
Plant Height – Short (t)

5. Task#6-1
Cut this flap in half.
(just like we did with the photosynthesis
C.R. foldable)
Genotype vs. Phenotype
Task#7-1
Cut this flap in half.
(just like we did with the photosynthesis
C.R. foldable)
Homozygous vs. Heterozygous

6. Task#6-2
Genotype
On your flap (above the title) write the
following:
Genotype: the two alleles (or
two letters) that represent the
genetic make up of an
organism
Example:
Plant Height – Tall (TT. Tt)
- Short (tt)
Task#6-3
Phenotype
On your flap (above the title) write the
following:
Phenotype: the PHYSICAL
appearance of a genotype
Example:
Plant Height – Tall or
- Short

7. Task#7-2
Homozygous
On your flap (above the title) write the
following:
Homozygous: having two of
the SAME alleles
2 capitals
OR 2 lower case letters
Homo = Same (PUREBRED)
Example: Plant Height
Tall (TT) OR Short (tt)
Task#7-3
Heterozygous
On your flap (above the title) write the
following:
Heterozygous: having two of
different alleles
1 capital AND
1 lower case letter
Hetero = Different (HYBRID)
Example: Plant Height
Tall (Tt)

8. Task#8
Punnett Squares
On your flap (above the title) write the following:
Probability: a branch of math that helps you predict the chance the something
will happen
Punnett Square: a tool
used in Mendelian
Genetics to predict the
results of a genetic cross
(probability); shows all the
possible combinations of
alleles
