Inheritance where both alleles are expressed in the offspring What is incomplete dominance? Return

Chart showing a trait from generation to generation What is a pedigree? Return

More than one set of genes controls a trait What is polygenic inheritance? Return

Physical appearance resulting from the pairs of genes for a trait What is phenotype? Return

What is homozygous? A trait with two alleles that are the same Return

Genetic make-up of an organism What is genotype? Return

An allele that is hidden in heterozygous genotypes What is recessive? Return

Study of how alleles affect offspring What is genetics? Return

DAILY DOUBLE DAILY DOUBLE

Different forms of the same gene What are alleles? Return

Passing of traits from one generation to the next What is heredity? Return

A disease where thick mucus is produced in lungs and the digestive system What is cystic fibrosis? Return

The probability that a baby will be a boy What is 1/2? Return

Genetic engineering has already helped people this way. What is increasing our food supply? Return

What is on the X chromosome? Hemophilia results from an allele found here. Return

Sickle-cell anemia is an example of this. What is a homozygous recessive disorder? Return

Blood type inheritance is an example of this. What is multiple alleles? Return

A red 4 o’clock crossed with a white 4 o’clock to produce a pink 4 o’clock is an example of this. What is incomplete dominance? Return

The combination of Tt represents a ____ genotype. What is heterozygous? Return

In a Punnett square, a capital letter (T) stands for this kind of allele. What is dominant? Return

He is considered to be the father of genetics. Who is Mendel? Return

A person who does not have the disorder but has a normal gene paired with a gene for the disorder is called this. What is a carrier? Return

Hair color in humans is inherited this way. What is polygenic inheritance? Return

If a father is a hemophiliac, why do none of his sons have it? The father passes the Y onto his sons which doesn’t contain the gene for hemophilia. Return

The genotype for a half-filled circle in a pedigree showing hemophilia What is X H X h ? Return

The phenotype of a person with genotype X H X h if H=normal blood clotting and h=hemophilia What is a normal blood clotter? Return

FINAL JEOPARDY ? Sex-Linked Trait

This is why sex-linked conditions show up more in males than in females. A female needs 2 of the recessive genes to have the condition while the males need just one because the gene is carried on the X chromosome but not the Y.

The genotype of a person represented by an empty square on a pedigree to track hemophila What is X H Y?

The phenotype of a person with genotype X H Y for the trait of hemophilia What is a normal clotter?

The probability of a person represented by an empty circle on a pedigree passing on the hemophilia trait What is 0%?

The probability in percent of a person represented by a filled-in square on a pedigree passing on the hemophilia trait What is 50%?

The probability in percent of a person represented as a half-filled circle on a pedigree passing on the hemophilia trait What is 50%?
