$100 Question-Mendel
What is Mendel’s first
Law?
$100 Answer from Mendel
Organisms inherit two copies of
Genes; one from each parent
Called the Law of Segregation
$200 Question from
Mendel
What are the physical characteristics
Or traits of an organism?
$300 Question Mendel
Phenotype
$300 Question Mendel
The exchange of chromosom
segments between hologous
chromosomes during Prophase I
of Meiosis 1?
$300 Answer Mendel
Crossing Over
$400 Question from
Mendel
Two pea plants were both grown
from green peas. When the plants
were crossed, their offspring
produced green, yellow, white peas.
Why?
$400 Answer Mendel
Sexual reproduction
has produced new
combination of alleles
$500 Question Mendel
Genes that are on two different
Chromosomes are said to
Exhibit independent assortment
Because….
$500 Answer Mendel
Are replicated independently of
Each other
$100 Question
Punnett Square
What does it mean to be homozygous?
$100 Answer
Punnett Square
Characteristic (GG or gg) of
having two of the same alleles at
the same locus of sister chromatids
$200 Question
Punnett Square
What is Heteroyzgous?
$200 Answer
Punnett Square
Characteristic of having two different alleles (Gg)
That appaear at the same locus of
Sister chromatids
$300 Question
Punnett Square
What is a testcross?
$300 Answer
Punnett Square
A cross between an
organism with an
unknown genotype
and an organism with
a recessive phenotype
$400 Question
Punnet Square
What must happen before
You can begin a Punnett
Square for a dihybrid cross?:
$400 Answer
Punnett Square
You need to
establish the
Gametes first
$500 Question
Punnet Square
The allele that causes muscular dystrophy
Is X-linked; recessive allele is Xf. If an XFXF
female and an XfY male have children, what
percentage of the male’s offspring would be
expected to inherit
Muscular dystrophy?
$500 Answer
Punnett Square
0%--because male (X) is
dominate
$100 Question-Genetics
A mutation has occurred in
A gene on chromosome 3.
How could this be passed
Along to offspring?
$100 Answer Genetics
in a sex cell that undergoes
fertilization
$200 Question
Genetics
Two mice, A and B have sex; the resulting
Offspring have half of the DNA from A
And half from B. Why?
$200 Answer
Genetics
Each parent contributes one
Set of chromosomes to each
offspring
$300 Question
Genetcs
What is the genotype of a male?
$300 Answer
Genetics
XY
$400 Question
Genetics
If two traits are not always inherited
Togther by the offpspring then what
Must be true?
$400 Answer
Genetics
The genes are far enough apart
To allow crossing over
$500 Question
Genetics
What is Mendel’s Second
Law called—allele pairs
separate independently
of each other during
gamete formation?
$500 Answer
Genetics
Law of Independent
Assortment
$100 Question Misc

cells have two copies of each
chromosomes?
$300 Answer Misc
Diploid.
.
$400 Question Misc

$400 Answer Msic.
Any of the alternative forms of a
gene that may occurs at a specific
locus
$500 Question Misc
What is a gene?
$500 Answer Misc.
A piece of DNA that provides a
set of instructions to
a cell to make a certain protein
Final Jeopardy
How can the environment impact a
gene?
Final Jeopardy Answer
The expression of genes in an organism can be influenced by
the environment, including the external world in which the
organism is located or develops, as well as the organism's
internal world, which includes such factors as its hormones and
metabolism. One major internal environmental influence that
affects gene expression is gender, as is the case with sexinfluenced and sex-limited traits. Similarly, drugs, chemicals,
temperature, and light are among the external environmental
factors that can determine which genes are turned on and off,
thereby influencing the way an organism develops and
functions.
