$100 Question-Mendel

What is Mendel’s first Law?

$100 Answer from Mendel

Organisms inherit two copies ofGenes; one from each parentCalled the Law of Segregation

$200 Question from Mendel

What are the physical characteristicsOr traits of an organism?

Phenotype

$300 Question Mendel

$300 Question Mendel

The exchange of chromosom segments between hologous

chromosomes during Prophase Iof 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 reproductionhas produced new

combination of alleles

$500 Question Mendel

Genes that are on two differentChromosomes are said to Exhibit independent assortment Because….

$500 Answer Mendel

Are replicated independently ofEach 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 AnswerPunnett 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 AnswerPunnett Square

A cross between an organism with an unknown genotype and an organism with a recessive phenotype

$400 Question Punnet Square

What must happen beforeYou 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 dystrophyIs 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 inheritMuscular dystrophy?

$500 Answer Punnett Square

0%--because male (X) is dominate

Final Jeopardy

How can the environment impact a gene?

Final Jeopardy AnswerThe 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 sex-influenced 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.
