An individual with the sex chromosomes XX will be _________ and an individual with the sex chromosomes XY will be ________.

Mendel's Law of Segregation states...

The pedigree shows the inheritance of color-blindness, a sex-linked recessive disorder.

If individual 3 is a carrier and marries a man with normal color vision, what is the chance their SON is color blind?

In owls eye color is a sex linked trait where yellow eyes are dominant to the orange eye phenotype. If a yellow eyed male is crossed with a female who carries the orange eye gene, what is likelihood of having an offspring with orange eyes?

The coloring of the snakes in the photo can vary: they can be beautifully marked with dark cross bands on a brown and yellow ground color or completely brown or black. Their color is specifically controlled by 4 genes with more dominant alleles creating more banding and more recessive alleles creating a more solid scale color.

In heavily-vegetated wetlands solid colored individuals are more difficult for predators to locate. Which genotype below would be most successful at camouflage in the heavily-vegetated wetlands?

In some horses the genes for brown hair and for white hair are codominant. The codominant condition gives the horses a reddish color, and is referred to as roan. If a roan stallion is bred with a white mare, what is the probability of them having a roan offspring?

In snapdragon flowers petal coloration is incompletely dominant with petals either being red, white, or pink. If two plants are bred creating several hundred offspring all of which are pink what would be the most likely phenotypes of the parent plants?

Brown (B) is dominant over white (b). Which genotype is a purebred for brown fur?

For pea plants, purple flowers are dominant to white flowers. A botanist crosses two pure breeding pea plants, one with purple flowers and one with white flowers, then use those offspring to produce a F₂ generation. What would be the genotypic ratio for seed color in the F₂ generation?

In pea plants, yellow seeds (Y) are dominant green seeds (y) and green pods (G) are dominant to yellow pods (g). Based of the punnett square, what is the probability of producing a pea plant with green seeds in a yellow pod?

Hemophilia is a recessive x-linked disorder.

Which genotype represents a male with hemophilia?

Which set of parents can most likely produce a child with type O blood?

If two heterozygous individuals are crossed, what percent of their offspring are also expected to be heterozygous?

Deafness is a recessive trait for dogs. A deaf dog and a hearing dog whose father was deaf have puppies. What is the chance their puppies will be deaf?
