In guinea pigs, black fur is dominant to white

Complete a punnett square and show the genotypic ratio for a cross between a purebred black and a hybrid black guinea pig

In pea plants, green is dominant to yellow for pod color

What cross would result in ½ of the offspring having green pods and ½ of the offspring having yellow pods?

In pea plants, tall is dominant for plant height

When a tall plant is crossed with a short plant, some of the offspring are short. What are the genotypes of the parents? What are the genotypic and phenotypic ratios of the offspring?

In pea plants, terminal flowers are recessive

¾ of the plants produced by a cross between two unknown pea plants have axial flowers and ¼ have terminal flowers. Identify the genotype and phenotype of the parents

In pea plants, smooth pods are dominant to constricted

Cross a plant that is hybrid for smooth pods with a plant that is true breeding for constricted pods. Include the genotypic and phenotypic ratios for the offspring

Green is dominant for pea pod color as are smooth pods

Show the outcomes of independent assortment for an individual that is homozygous dominant for pod color and is heterozygous for smooth pods

In mice, running is dominant to waltzing and black fur is dominant to

brownCross a homozygous running heterozygous black mouse, with a heterozygous running brown mouse

Curved eyebrows are dominant to straight and green eyes are recessive

to brownIf a heterozygous curved eyebrow green eyed individual is crossed with a straight eyebrow heterozygous brown eyed parent, what will be the phenotypic ratio of the offspring

In snapdragon flowers, red flowers are dominant to white and tall are

dominant to short

Identify the genotypes of the parents that will produce a 9:3:3:1 phenotypic ratio in the offspring

In mice, running is dominant to waltzing and black fur is dominant to

brownPredict the genotypic and phenotypic ratios for a cross between two mice who are waltzing and brown

Colorblindness is recessive and is carried on the X chromosome

Determine the possible genotypes for the parents of a girl who is colorblind

Colorblindness is recessive and is carried on the X chromosome

Determine the probability of a son being colorblind to these parents:Mother is a carrier and father is color blind

Hemophilia is a recessive disorder carried on the X chromosome

Determine the possible phenotypes of offspring for a mother who is a carrier and a father who does not have hemophilia. Use a punnett square

Eye color is sex-linked in fruit flies with red eyes being dominant to white

Show the cross between a heterozygous red female and a red eyed male fruit fly

The tortoise shell gene is on the X chromosome in cats

If a cat is tortoise shell in appearance is it most likely a male or female? Why?

In Four O’Clock flowers, many colors are observed

A true breeding red flower was crossed with a true breeding white. All of the F1 generation was pink. In the F2 generation there were pink, red, and white flowers present. Name the inheritance pattern

In tulips red, blue, and purple are present as flower colors

When a red and blue tulip are crossed, purple flowers are produced. Identify the genotype of a red flower, a blue flower, and a purple flower

When a black guinea pig is crossed with a white guinea pig, the offspring

are black and white

Make a punnett square showing a cross between a black guinea pig and a spotted guinea pig. Indicate the possible genotypes and phenotypes of the offspring

Purple flowers result from a cross between a red and blue tulip

Show a cross between two purple tulips. Indicate the genotypic and phenotypic ratios from the cross

Cattle may have a red coat, a white coat, or a roan coat (red and white

hairs)

A red cow is crossed with a white cow and the offspring are roan. Name the inheritance pattern
