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.

In the snail Limnaea peregra, coiling of the shell is determined by the genes D for right-handed coiled shells, and d for left-handed coiled shells. The gene for the right-handed shell is dominant. However, the direction of coiling in any single individual is determined by the genotype of the maternal parent producing the egg, regardless of the progeny's genotype. Which describes this type of inheritance?
A. infectious heredity
B. maternal effect
C. dominant X-linked
D. organelle heredity
This pedigree traces the inheritance of a rare disease in humans.
a. Based on this pedigree, is the allele for this disease dominant or recessive? Explain.
b. What genotypes are possible for the individuals labeled 1, 2, and 3?

- Duchenne muscular dystrophy is sex linked and usually affects only males. Victims of the disease become progressively weaker, starting early in life.a. What is the probability that a woman whose brother has Duchenne’s disease will have an affected child?b. If your mother’s brother (your uncle) had Duchenne’s disease, what is the probability that you have received the allele?c. If your father’s brother had the disease, what is the probability that you have received the allele?arrow_forwardSickle cell anemia is an inherited red blood cell disorder in which there are not enough healthy red blood cells to carry oxygen throughout the body. The allele that causes sickle-cell anemia is autosomal recessive (s), and the dominant allele can be represented by S. How many offspring will be affected by the disorder if the mother is a carrier, and the father appears to be normal? (Include the gender) a. b. How many will become carriers?

It is caused by a mutant allele of the fibroblast growth factor receptor 3 gene ( FGFR3) that produces an overactive protein. Having one copy of the mutant allele results in dwarfism. Two copies of the mutant allele results in death before birth. The mutant FGFR3 allele is completely penetrant. 1. What can you infer about the inheritance of the FGFR alleles? A) The mutant FGFR3 allele is pleiotropic. B) Some achondroplastic dwarfs are heterozygous for the mutant allele and some are homozygous. C) The wild-type and mutant FGFR3 alleles are codominant. D) The mutant FGFR3 allele shows incomplete penetrance. 2. If two people with achondroplasia have a child together, what is the probability that their child will also have achondroplasia?

One parent is homozygous for a Tay–Sachs allele,and the other is heterozygous.arrow_forwardColor blindness in humans is controlled by an X-linked completely recessive allele (Xc), while breast cancer is controlled by an autosomal completely dominant allele, B. A color blind male, who is a heterozygote carrier for breast cancer has three children/n with a normal eyed female (whose mother was color blind), who is homozygote recessive for the breast cancer allele. What is the probability that out of three children, 2 will be color blind males, and not show breast cancer, and one will be a color blind female, who shows breast cancer?arrow_forwardIn 1995, doctors reported a Chinese family in whichretinitis pigmentosa (progressive degeneration of theretina leading to blindness) affected only males. Allsix sons of affected males were affected, but all of thefive daughters of affected males (and all of thechildren of these daughters) were unaffected.a. What is the likelihood that this form of retinitispigmentosa is due to an autosomal mutationshowing complete dominance?b. What other possibilities could explain the inheritance of retinitis pigmentosa in this family? Whichof these possibilities do you think is most likely?arrow_forward
- Ectrodactyly is a rare condition in which the fingers are absent and the hand is split. This condition is usually inherited as an autosomal dominant trait.

If not, what mode of inheritance is most likely? Explain your reasoning.arrow_forwardEctrodactyly is a rare condition in which the fingers are absent and the hand is split.
