15. The following pedigree shows inheritance of Huntington's disease, a fatal genetic
disorder that causes neurodegeneration. Since signs and symptoms usually do not
appear until adulthood, many who are carriers may not realize their risk of passing on
the disease-causing allele. The following pedigree represents a family in which some
people are affected by Huntington's disease.

a. Determine if the pedigree below can be for a trait that is X-linked traits. Write the genotype of each individual next to the symbol.
b. Is it possible that this pedigree is for an X-linked recessive trait?
c. What can you conclude about the children if both parents are affected with an X-linked recessive trait?

One mutant recessive trait in fruit flies is called "eyeless" because it causes flies to have no eyes. Cross an eyeless fly with a homozygous normal fly. a. Draw the Punnett square. b. What is the genotyoe ratio of the offspring? c. What is the phenotype ratio of the offspring? d. What genetic problem is this? (monohybrid, dihybrid or multiple allele)arrow_forwardDeaf mutism, a form of deafness in humans, is a type in which the individual inherits not only deafness but also the inability to talk. A sample pedigree of deaf mutism is shown in the picture. Provide your explanation for the inheritance of this condition in the two families in generation.arrow_forward
- What are the genotypes of the mother and father in the pedigree below? The pedigree shows albinism (an autosomal recessive trait). The shaded shapes represent albino individuals. a. mother - homozygous dominant; father - homozygous dominant b. mother - heterozygous; father - homozygous recessive c. mother - homozygous recessive; father - heterozygous d. mother - heterozygous; father - heterozygous e. mother - homozygous dominant; father - homozygous recessivearrow_forwardThe chart below is showing 4 generations of a family that is affected by a hereditary disease. a. Is the disorder being tracked dominant or recessive? How do you know? b. There is only one possible genotype for person C. True or False? c. What are the possible genotypes for person A? d. What are the possible genotypes for person B?, e. If two people with the same genotypes as person C's spouse and person A's spouse had a child, what is the probability that the child will be affected by this genetic disorder? (draw a Punnett square using the correct genotypes to help you). % chance offspring will be affected % chance offspring will not be affectedarrow_forwardIn cats, the gene for calico (multicolored) cats is both sex-linked and codominant. Due to a phenomenon known as dosage compensation, females that receive a B and an R gene have black and orange splotches on white Males can only be black or orange, but never calico. a. What would a calico cat’s genotype be? b. Show the cross of a female calico cat with a black male. What percentage of the kittens will be black and male? c. What percentage of the kittens will be calico and male? d. What percentage of the kittens will be calico and female? e. Show the cross of a female black cat with a male orange cat. f.

- In certain breeds of chicken, the appearance of the comb (a fleshy growth or crest on the top of the head of gallinaceous birds, such as turkeys, pheasants, and domestic chickens) is controlled by a single pair of genes. One type of comb, the pea comb, is dominant over a single comb. You own a rooster with a single comb. M a. What is the genotype of your rooster? b. Suppose you cross your rooster is crossed your neighbor's pea- combed hen. The brood of 13 eggs that is produced hatches to Single reveal 5 have single combs and 7 have pea combs. What was the genotype of your neighbor's hem? (Use a Punnett square to determine your results). Peaarrow_forwardLorenzo has a double row of eyelashes (MIM 126300) which he inherited from his mother as a dominant trait. His maternal grandfather is the only other relative to have it. Fatima, who has normal eyelashes, marries Lorenzo. The first child, Nicola (girl) has normal eyelashes. Now Fatima is pregnant again and hopes for a child with double eyelashes. What chance does the child have of inheriting double eyelashes? Draw a pedigree of this family.arrow_forwardBill is color blind and has developed Huntington’s disease. His mother has normal vision and does not have Huntington’s disease. Susan does not have Huntington’s disease and has normal vision. Her mother is normal in all respects, but her father is color blind and suffers from Huntington’s disease. Bill's father is not color blind or have huntington's disease. a. Make a pedigree and indicate the alleles for each individuals traits. b. If Bill and Susan marry, and ignoring the fact that Huntington’s disease is lethal, what types and proportions of children can they produce? c. If Bill and Susan marry, what is the probability that the first two children will be color blind females without HD, the third child will be a color blind male with Huntington.arrow_forward
- Tay–Sachs disease is caused by recessive alleles on anautosome. In which case(s) could two parents with anormal phenotype have a child with Tay–Sachs?a. Both parents are homozygous for a Tay–Sachs allele.b. Both parents are heterozygous for a Tay–Sachsallele.c. One parent is homozygous for a Tay–Sachs allele,and the other is heterozygous.arrow_forwardA breeder is interested in a new coat colour in mice. This trait is controlled by a single autosomal gene (Gene T) with two alleles. The T-allele results in a yellow coat colour, while the recessive allele causes a cream coat colour. The breeder has a yellow mouse. Can you suggest how the breeder can determine the genotype (TT or Tt) of his mouse in a single cross? Describe this cross and provide details on how you would interpret the results.arrow_forwardTay-Sachs disease is a rare human disease in which toxic substances accumulate in nerve cells. The recessive allele responsible for the disease is inherited in a simple Mendelian manner. For unknown reasons, the allele is more common in populations of Ashkenazi Jews of eastern Europe. A woman is planning to marry her first cousin, but the couple discovers that their shared grandfather’s sister died in infancy of Tay-Sachs disease.a. Draw the relevant parts of the pedigree, and show all the genotypes as completely as possible. b. What is the probability that the cousins’ first child will have Tay-Sachs disease, assuming that all people who marry into the family are homozygous normal?arrow_forward
