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

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…..
A
B
Rh
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!)
