A plant with red flowers (IRIR) is crossed with a plant that has white flowers (IWIW). What percentage of the offspring will have pink flowers?

One of the co-dominant traits studied in class was blood types. If a person has the allele blood type IBi what type of blood type does the individual have?

Cross a roan cow (pictured here IRIW) with a white cow (IWIW), what will be the resulting phenotypic ratio of the offspring?

A white mouse with red eyes is crossed with a black mouse with brown eyes. The white mouse is recessive for both of its traits. The black mouse is dominant for both of its traits.

This cross would be

What is the fraction of the parakeets from this cross that would look like the first parent in P1?

Suppose that black hair (B) is dominant over blonde hair (b) and brown eyes (E) are dominant over blue eyes (e).

The father has black hair (heterozygous) and brown eyes (heterozygous) and the mother has blonde hair and blue eyes.

What is the ratio for the genotypes for the offspring?

A tall green pea plant (TTGG) is crossed with a short white pea plant (ttgg). What is the ratio for the genotypes of the offspring?

What information can you gather about the pictured monohybrid cross? (Select all that apply!)

In chickens, feather color is codominant. If a black chicken IBIB is mated with one that is black and white (IBIW) what are the chances of having a chicken that is black and white?

Round seeds (R) are dominant to wrinkled seeds (r) in pea plants. If two heterozygous parents are crossed, what is the genotypic ratio?

Sickle cell anemia is an autosomal recessive disorder that affects the ability of blood to clot. If a woman with sickle cell anemia has children with a man who is heterozygous for sickle cell, what are the chances their child will have the disorder?

Blood type exhibits multiple alleles and codominance. There are 4 blood types: A, B, AB, and O. If a heterozygous type B man and a type AB woman want to have a child, what are the chances that they will have a type B child?

Duchenne muscular dystrophy (DMD) is a recessive sex-linked disorder which results in muscle degeneration. If a mother who is a carrier has children with a man who does not have DMD, what are the chances of their son having the disorder?

A woman has the genotype of ii for her blood type. Her mother is heterozygous for A type. Which genotype can her father be?

Fur color in guinea pigs is a codominant trait. A guinea pig with black and white fur has offspring with a guinea pig with white fur. What are the chances their baby will have black fur?

Cross Two Homozygous plants

(RRYY x rryy)

R = round seeds, r = wrinkled seeds Y = yellow seeds, y = green seeds

What percent will have Round and Yellow seeds?

Hemophilia is a recessive x-linked disorder.
