Genes 100
Trait passed from parent to
offspring.
What is an inherited trait?
Genes 200
An observable or measureable
version of a characteristic.
What is a trait?
Genes 300
A genetic disease that results in
changes to the body’s
connective tissue.
What is Marfan Syndrome?
Genes 400
The only human cells that do not have
46 chromosomes.
What are sex cells?
Genes 500
Explain what determines the gender
of a child. Include the alleles for
males and females.
What is the given by the father (X or Y).
A female is XX and a male is XY.
Copycat 100
The process of producing
offspring where there is only 1
parent and offspring are exact
copies of the parent.
What is asexual reproduction?
Copycat 200
The union of sperm and egg.
What is fertilization?
Copycat 300
The process of joining two sex
cells to produce unique
individuals with inherited traits
from both parents.
What is sexual reproduction?
Copycat 400
An offspring produced by asexual
reproduction.
What is a clone?
Copycat 500
Only one fertilization occurs, but
two organisms are produced.
What are identical twins?
Pea Plants 100
The father of genetics.
Who is Gregor Mendel?
Pea Plants 200
When Mendel crossed pure white
flowering pea plants with pure purple
flowering plants, all the offspring
were purple. This and similar
observations led to the this theory.
What is that there is a dominant version (purple)
and a recessive version (white) of the gene for
flower color.
Pea Plants 300
What Mendel theorized when
he observed 2 purple flowering
plants produced white
flowering offspring.
What is white is a recessive trait that
was hidden in Generation 2
Pea Plants 400
The inheritance pattern that
results in offspring with ¾
dominant trait and ¼ recessive
trait.
What is the 3:1 dominant to recessive
pattern that results from cross of two
heterozygous dominant parents. (as in
Mendel’s Gen 2 resulting in Gen 3)
Pea Plants 500.
For one table group, the results for
growing Nicotiana seeds was a 2:1
green to light yellow ratio. Explain.
What is that we did not have a big enough
sample size and so the actual results did not
reach the theoretical 3:1 ratio.
Squares 100
A diagram used to show the likely
outcome of a breeding experiment
with parents with known alleles.
What is a Punnett Square?
Squares 200
Skye’s genotype for tail color
(blue tailed creature with all
blue tailed ancestors).
What is homozygous dominant TT?
Squares 300
Ocean and Lucy were two of Sky
and Poppy’s offspring with this
same genotype and phenotype
for tail color.
What is blue with a heterozygous
dominant Tt genotype?
Squares 400
If white fur is dominant, and we
cross two rats with the genotype Ff,
what phenotype (color fur) will the
offspring have?
What is the 3:1 dominant to recessive inheritance
pattern that theoretically results in ¾ white and ¼
black rats?
Squares 500
The theoretical result of crossing a
heterozygous dominant blue tailed
creature with a homozygous
recessive orange tailed creature.
What is ½ orange (tt) and ½ blue
(Tt)tails.
Vocabulary 100
Unless two versions of this gene
are present, the trait is hidden.
What is a recessive?
Vocabulary 200
Different versions of a gene.
What is an allele?
Vocabulary 300
When the 2 versions of an allele are
the same.
What is homozygous?
Vocabulary 400
A diagram of a family tree often used
for genetic analysis.
What is a pedigree?
Vocabulary 500
The result of an error that occurs
during the copying of DNA.
What is a mutation?
