1. Non Mendelian Genetics Foldable

2. Fold your paper so you have 2 flaps opposite each other
Next cut four divisions on each side. You should have a total of 8, four on each side.
Label the left side: CoDominance, Incomplete Dominance, Polygenetic, Gametes,
Label the 1st flap on the right side Multiple Alleles, label the 2nd flap Epistasis, 3rd flap Autosomes and the 4th flap Sex-Linked
Non-Mendelian Genetics
CoDominance
Multiple Alleles
Incomplete Dominance
Epistasis
Polygenetic
Autosomes
Gametes
Sex-Linked

3. Codominance Under the codominance flap write:
Both alleles contribute to phenotype
Normal blood cells x Sickle blood cells = both normal and sickle cell blood.
In this case it would be a positive change. People who are carriers for sickle cell disease are protected against Malaria!

4. Incomplete Dominance On the first flap write:
Heterozygous phenotype is halfway in between the two homozygous phenotypes
Red flower x white flower = pink flower!!!
RR X WW = RW

5. Multiple Alleles Under the first flap write:
Many genes have MORE than two alleles
Human blood type (A, B, O)
Blood type is written
with the letter I to
represent
A and B which are
codominate and i to
represent O which is
recessive.

6. Epistasis Under the 2nd flap write:
the effect of one gene is dependent on the presence of one or more 'modifier genes', i.e. the genetic background

7. Polygenic Traits Under the polygenic flap write:
Traits produced by interaction of more than one gene
Human skin color and
height
Always makes a bell
shaped curve

8. XX or XY Gametes Write the following under the gamete flap
Gametes are sex cells, they have ½ the number of chromosomes as autosomes (23 instead of 46)
Male gamete –sperm
Female gamete – egg
The gene for sex if on the Y chromosome so the Male decides the sex of the baby. 50 to 50 chance of having a male or female
XX or XY

9. Autosomes Under the flap write The other 22 pair of chromosomes
Carry information about everything else except sex
Autosomal mutations
are not passed to
offspring.
Ex. skin cancer

10. Sex linked disorders Under the flap write:
Sex link traits are traits carried on the X chromosome.
Males have a 50 percent chance of inheriting a sex linked disorder. Females
have a 25 percent chance.
Examples: color blindness,
hemophilia,
muscular dystrophy
