In a family where the mother is a carrier of hemophilia (an X-linked recessive disorder) and the father is healthy, what is the probability that they will have a daughter that is a carrier?

If a particular disease is passed down by Y chromosomes, what is the probability that a girl will inherit the disease?

In English bulldogs, gray fur and brown eyes are both considered dominant traits. Abigail, a part-time English bulldog breeder, crosses a white-furred and blue-eyed bulldog with a bulldog who is homozygous for gray fur and heterozygous for brown eyes.

What are the possible gametes that the white-furred and blue-eyed bulldog can make?

In English bulldogs, gray fur and brown eyes are both considered dominant traits. Abigail, a part-time English bulldog breeder, crosses a white-furred and blue-eyed bulldog with a bulldog who is homozygous for gray fur and heterozygous for brown eyes.

What is the genotype of the white-furred and blue-eyed bulldog?

In fish, curved fins are dominant to sharp fins and thin bodies are dominant to thick bodies.

A male with the genotype CcSS mates with a female with the genotype CCss.

Which of the following genotypes is not possible in the offspring of this cross?

In rose plants, red-colored petals are dominant to white-colored petals and thorns are dominant to no thorns. A heterozygous red rose plant that is homozygous for no thorns is crossed with a homozygous white rose plant that is heterozygous for thorns.

Question: What is the probability of having a rose plant offspring that has red petals and no thorns?

How many of the predicted offspring from the cross above, will be square and yellow?

How many of the predicted offspring would be Tall & Black?

In English bulldogs, gray fur and brown eyes are both considered dominant traits. Abigail, a part-time English bulldog breeder, crosses a white-furred and blue-eyed bulldog with a bulldog who is homozygous for gray fur and heterozygous for brown eyes.

Question: What are the expected phenotypes of their offspring?

In penguins, happy feet is dominant to sad feet and singing is dominant to no singing. A penguin that is heterozygous for both happy feet and singing mates with a penguin that has sad feet and cannot sing.

Question: What is the probability of having a penguin with happy feet who does not sing?

In humans, being right-handed is dominant to being left-handed and having brown eyes is dominant to having blue eyes. A man who is heterozygous for both traits "falls in love" with a woman who is also heterozygous for both traits.

Question: What is the expected phenotypic ratio from this dihybrid cross?

In fish, fast swimmers (F) are dominant to slow swimmers (f) and long fins (L) are dominant to short fins (l). Given the cross: FFLL x ffll

What is the probability of an offspring being fast with long fins?

In flowers, tall stems are dominant to short stems and red color is dominant to white.

What traits would a flower with the genotype Ttrr have?

In dogs, black hair is dominant to white hair and coarse hair is dominant to fine hair.

The dihybrid shows the cross: Bbcc x bbCc

Based on the information given, select all offspring that have black and coarse hair.

Antelopes have two unlined allele pairs that affect their horn type. They can have twisted longhorns, twisted shorthorns, or straight horns. If they have the genotype hh, they have straight horns no matter what other alleles they have.

What is the probability of straight horns (hh) in the offspring of a cross between two antelope with TtHh alleles?

In humans, being tall is dominant to short, and having a widow's peak in dominant to having a straight hairline. Two individuals who are BOTH heterozygous for both traits are crossed and data is as shown in the table below.
