The pedigree below is showing a recessive autosomal trait (blue eyes). What would be the genotype of III-3?

If you crossed two heterozygous individuals, their

offspring would have

A) 0% Homozygous recessiveB) 25% HeterozygousC) 75% Dominant PhenotypeD) 50% Recessive Phenotype

A Red flower is crossed with a white flower, the offspring are

pink, this is an example of what kind of dominance?

The alternative form of a gene is called an:

Blood types are an example of these two types of inheritance...

Two plants are crossed, resulting in offspring with a 3:1 ratio for a trait.

What does this suggest?

A) That both parents were heterozygousB) That each offspring has the same

allelesC) That the parents were pure breedsD) That blending of traits occurred.

Using this pedigree, individuals with the arrows are

A) HeterozygousB) Homozygous DominantC) Homozygous RecessiveD) Genotype unknown

who blood clots normally.

A) What is the chance they will have a child that has hemophilia?

B) What is the chance that they have a daughter with hemophilia?

C) What about a son?

Two parents have the genotype Gg for a dominant genetic disorder.

What are the chances their offspring will have the disorder?

Which of the following is NOT true about carriers?

A) They only can be femalesB) They express the disorderC) They can pass on the recessive alleleD) Males cannot be carriers

The ability to roll your tongue is dominant to not being able to roll your tongue. Draw a pedigree to show the

inheritance of this trait, given the following family history:

Grandpa Snow is a tongue roller but Grandma Snow is not. They have four children (2 sons and 2 daughters) who are all rollers. Their last daughter, Judy, married John Flake. John’s parents are both rollers, but John’s two sisters are non-rollers. John is a roller. John and Judy Snow-Flake have three children named Crystal

Snow-Flake (a non-roller), Pretty Snow-Flake (a roller) and Jake Snow-Flake (a roller).

For two heterozygous individuals, their offspring would yield the

phenotype ratio of _____ and the genotype ratio of _____.

If a family has 4 girls, what are the chances of their next child

being a boy?

The arctic fox changing fur color between seasons is caused by

A)

B)

C)

D)

Color blindness is recessive and sex linked. On average there are more color blind males because

A) Women need two alleles to be colorblindB) Men require two alleles to be colorblindC) Women have two X chromosomes and it is inherited on the Y chromosomeD) Men are more likely due to chance

Name that blood type…..

Two roan cows are crossed. What are the phenotypic ratio of

the offspring?

BbRr x BbRr are crossed. What are the phenotypic ratio of the

offspring?

A) 3:1B) 1:2:1C) 1:1:1:1D) 9:3:3:1

Parents, one heterozygous for two traits and the other homozygous

recessive for two traits, produce_______ offspring that are

homozygous dominant for both traits A) 100%B) 75%C) 25%D) 0%

Straight hair is recessive and curly hair is dominant. In co-dominance, the heterozygous condition would be

A) CurlyB) StraightC) WavyD) Some straight hairs, some wavy hairs

When an organism has a heterozygous genotype, the

dominant trait is seen. This can be explained by which law?

Draw a pedigree using the information below. Be sure to include EVERYTHING that should be in a pedigree. Then

answer the question…

A man and woman marry. They have five children, 2 girls and 3 boys. The mother is a carrier of hemophilia, an X-linked

disorder. She passes the gene on to two of the boys who died in childhood and one of the daughters is also a carrier. Both

daughters marry men without hemophilia and have 3 children (2 boys and a girl). The carrier daughter has one son with

hemophilia. One of the non-carrier daughter's sons marries a woman who is a carrier and they have twin daughters.

What is the percent chance that either of the twins will also be a carrier?

Give me the genotypes of everyone in the pedigree! (Its sex-linked don’t forget!)
