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 DAILY DOUBLEDOUBLE

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 XHXh?

Return

The phenotype of a person with genotype XHXh 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 XHY?

The phenotype of a person with genotype XHYfor 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 personrepresented as a half-filled circle on apedigree passing on the hemophilia trait

What is 50%?
