Alkaptonuria is a metabolic disorder in which affected people produce black urine. Alkaptonuria results from an allele (a) that is recessive to the allele for normal metabolism (A). Sally has normal metabolism, buther brother has alkaptonuria. Sally’s father has alkaptonuria, and her mother has normal metabolism. Q. Give the genotypes of Sally, her mother, her father, and her brother.

Albinism is a recessive genetic condition in which a person lacks pigment that gives color to the skin. If the allele for albinism is represented as "a," and the functional allele is represented as "A," what will be the genotype of a person with albinism? Aa or AA Aa or aa AA aa
A is a dominant gene for normal pigment, and a is its recessive allele for albinism (and pink eyes). B is a dominant gene for brown eyes, and b is its recessive allele (blue). What is the mother's genotype if two brown-eyed parents have fraternal twins, one with blue eyes and one with pink eyes (albino)? a. AaBb b. AaBB c. aaBb d. aabb e. AABB
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?
Joan was born with six toes on each foot, a dominanttrait called polydactyly. Two of her five siblings and hermother, but not her father, also have extra digits. Whatis Joan’s genotype for the number-of-digits character?Explain your answer. Use D and d to symbolize the allelesfor this character.
Elizabeth is married to John, and they have four children. Elizabeth has a straight nose "n" (recessive) and dimples “D"(dominant). John has also dimples, but he has a convex nose “N"(dominant). Of their four children, Ellen is just like her father, and Dan is just like his mother. The other children-Anne, who has a convex nose, and Peter, who has a straight nose have no dimples "d”. Answer the following questions about this family: •What are the genotypes of Elizabeth and John? •Using a Punnett square determine possible genotypes of children. •Elizabeth's father was a straght-nosed/ dimples, while her mother was a convex-nosed/ dimples. What can you figure out about their genotypes? •John's father was a straight-nosed dimples, while his mother was convex- nosed/dimples. What can you determine about their genotypes?

In guinea pigs, the allele for short hair is dominant. If all the guinea pigs are born short haired what are the possible genotypes of the parents? (There are two possible combinations.) Show the answers with punnett square
Marfan’s syndrome is an example of pleiotrophy where individuals with a copy of the dominant allele have skeletal disorders, mitral valve prolapse and characteristic slender, loose joints. If Abraham Lincoln had a marfanoid disorder which he inherited from his mother, what are the chances he passed this trait on to his offspring? Consider that Mary Todd Lincoln, his wife, was 5’2”. please include a punnett square
In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the genotype of the woman's father? What is the probability that the couple's first child will be a non-freckled, normal visioned girl? What is the probability that the first two children born to the couple will be freckled and colorblind girls?
Write the genotype for each person based on : -Homozygous for B allele -Heterozygous for A allele -Type O -Type A and had a type O parent -Type AB -Blood that can be donated to anybody -Can only received blood from a type O donor There is a couple, the blood type of a male is A+ and the female is o+. What are all the possible blood types of their children in the future? Illustrate the inheritance in a Punnett Square showing all the possible blood types from the offspring of the male and female.
