In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
The allele for hitchhiker’s thumb (h) is recessive to straight thumb (H). If a man and his wife are both homozygous recessive, will any of their offspring potentially have hitchhikers thumb? What is the man’s genotype and the woman’s genotype? What is the man’s phenotype and the woman’s phenotype? What genotype(s) must the offspring have in order to have the phenotypic trait of hitchhiker’s thumb? Do a cross to determine all potential hitchhiker’s thumb genotypes and phenotypes for the offspring of this man and woman. Is it possible for any offspring of the F1 generation to have hitchhiker’s thumb?
The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. What percentage of their offspring will be carriers for the bell-shape trait? a.0% b.25% c.50% d.75% e.100%
in humans, normal skin pigmentation is influenced by a dominant gene (c), which allows pigmentation to develop. all individuals who are homozygous for the recessive allele (c) are unable to produce an enzyme needed for melanin formation and are therefore referred to as albino. two normal parents produce an albino child. what are the chances that the next child will be an albino? 1/2 chance 1/8 chance 2/3 chance no chance 1/4 chance
A pair of genes for the colour of the cat's is sex-linked. The dominant gene A produces a yellow coat, whereas the recessive gene a produces a black coat. A heterozygous gene (Aa) produces a tortoise colour. If a heterozygous female cat (Aa) breeds with a male cat that has a black coat (aa), what are the probable genotypes and phenotypes of their offspring?
In humans, the alleles for unattached earlobes is dominant over the allele for attached earlobes. The allele for dark hair dominates the allele for light hair. If both parents are heterozygous for earlobe attachment and hair color, what types of offspring can they produce, and what is the probability for each type?
The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape  while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. There is [blank] % that their next child will also be bell-shaped female like Hannah.
In humans, hair color and structure are determined by two independent pairs of genes. The dominant gene T  determines dark hair color, and the recessive allele t - light hair; The dominant gene S  determines the formation of curly hair, and its recessive allele t - straight hair. What kind of hair will the children have if the mother has light, straight hair, and the father has dark, curly hair (one of the pairs of traits is heterozygous for both parents)?
The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape  while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. If their next child is a boy, there is a _____% chance it will be round.
Albinism is an autosomal (not sex-linked) recessive trait. A man and woman are both of normal pigmentation and have one child out of three who is albino (without melanin pigmentation). What are the genotypes of the albino's parents? Both parents must be homozygous dominant. Both parents must be heterozygous. One parent must be homozygous dominant; the other parent must be heterozygous. One parent must be heterozygous; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. O O O O O
In domestic cats, the allele (L) is a dominant allele for short-hair trait. The recessive allele for long hair is (I). A female cat with a LI genotype has kittens with a male cat with a II genotype. What is the probability that a kitten has short hair? Hint: it may be helpful to draw a Punnett Square.
In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headaches are due to a dominant allele, and normal (no headaches) is recessive. A male who is heterozygous for blindness and does not suffer from headaches marries a woman who has normal vision and does not suffer from migraines. Could they produce a child with normal vision who does not suffer from headaches? If yes, can the probability of such a child be determined?
