Access the first link shown above. Click on ‘Tour of Basic Genetics’ then the ‘What
is a Gene’ Animation. Watch through this animation and fill in answers below.
1. What are genes? What function do they serve in our bodies?
2. What are our genes made of? _______________
3. One strand of our DNA contains ____________ genes.
4. What do these genes do in our bodies?
5. What causes a genetic disorder called Sickle Cell Anemia?
6. What Complex Inheritance Pattern does Sickle Cell Anemia follow? (In your
notes).
Still on the first link, now click on the ‘What is Heredity’ Animation. Watch
through this animation and fill in the blanks below.
1. Why do children have traits that resemble those of their parents and siblings have traits
that resemble each other?
2. What is the basis of heredity?
3. Our genes encode the ______________________ that define our _________.
4. Each of us has _________________of genes, which are made of _________ and reside
in our ____________________.
5. In addition to our DNA that we inherit from out parents, what else can affect our traits?
6. Human have two complete sets of ___________________.
7. When parents conceive a child, they contribute one complete set to the child (2 x 23 is
_______ total chromosomes in the human body.
8. While most cells in our bodies contain ___ sets of chromosomes (2 x 23 = 46), sperm
and egg cells each have only __ set (23). When they join they create a single cell called a
_________ which has two sets of chromosomes (46).
9. Why is it that some children will resemble their mother more, and some will resemble
their father more?
Still on the first link, now click on the ‘What is a Trait’ Animation. Watch
through this animation and fill in the blanks below.
1. What is a trait?
2. What are the different types of traits?
a.
b.
c.
3. The instructions encoded in our genes play a role in defining traits. But the ‘non-genetic’
or ______________________ influences in our lives are just as important in shaping our
traits. List a few examples of these below:
a.
b.
c.
4. Scientists call the set of genetic information for each form of a gene as a ___________.
5. The ‘Straight Thumb Allele’ H is (dominant/recessive) while the ‘Hitchhiker’s Thumb
Allele’ h is (dominant/recessive).
6. Homozygous means that:
7. According to Mendel, what happens when you have a Dominant allele and a Recessive
allele for the same gene? What is this Big letter-Little letter combination called?
8. Look at the slide where the different combinations of thumb types are shown that the
babies could inherit from their parents. What is the genotypic ratio of potential
outcomes and the phenotypic ratio of potential outcomes?
9. All traits do not work this easily, in the way that Mendel discovered. Explain the way
that inheritance works with the Complex Inheritance Pattern Incomplete Dominance.
Still on the first link, now click on the ‘What is a Chromosome’ Animation. Watch
through this animation and fill in the blanks below.
1. Chromosomes are efficient storage units for ________.
2. What is the image called when all of the chromosomes of the human body are
matched and lined up according to size?
3. Female Sex chromosomes are ___ ___ while the combination of sex chromosomes
for males is ___ ___.
