Use the terms from above to answer the questions below, and please know not all terms will be used.
1.
A homozygous trait is also referred to as this, dogs usually are sold for
more money ($) if this condition is met.
2.
The genetic makeup of an organism and this information is coded as a
nucleotide sequence within DNA.
3.
Another way to write “Female” (genotype).
4.
Three separate genotypes that have three separate phenotypes don’t
express a single dominant trait, rather all phenotypes act as dominant.
5.
A normal vision female and a normal vision male have a colorblind son.
The female in this scenario is known as what?
6.
The passing on of genetic factors: the transfer of genetically controlled
characteristics such as hair color or flower color from one generation to
the next in living organisms.
7.
A pair of alleles that are identical to each other, or “the same”.
8.
A trait that is not expressed when a dominant trait is in the genotype.
9.
The study of heredity.
10.
Traits that are always expressed in an organism’s phenotype.
11.
The “Physical” attributes of an organism (What you can see).
12.
Device used to calculate offspring and to predict chance (%).
13.
Every genotype is made of two__?
14.
The Grandfather of Genetics.
15.
When the offspring have been identified you can construct this to
determine the parents possible genotypes.
16.
A diagram that represents recessive traits passed from one generation to
the next. This visual diagram is extremely helpful tracing back many
generations.
17.
All genetic information (DNA) is bundled into this structure.
18.
A dominant and recessive trait in one genotype, also means “different”.
19.
A recessive trait that is linked to the “X” chromosome is a considered this
type of trait.
20.
Between two parents, this sex determines what gender the offspring will
be (answer should be expressed as a genotype).
BONUS
21.
Nucleotides form DNA, DNA forms chromosomes, and regions on the
chromosomes are coded for specific things (i.e.; size, shape, color, etc…). What
are these regions on a chromosome called?

____
2. Refer to the illustration above. Child # 3 probably has a homozygous recessive phenotype.
____
3. Refer to the illustration above. The family had 2 boys and 1 girl.
Multiple Choice
Identify the letter of the choice that best completes the statement or answers the question.

B. have an extra freckles chromosome.
C. be heterozygous for freckles.
D. have freckles chromosomes.
____
5. Refer to the illustration above. The genotype in box “3” of the Punnett square is
A. FF.
B. Ff.
C. ff.
D. None of the above
