Genes code for proteins that determine the phenotypes of individuals.

In individuals affected by cystic fibrosis, salt crystals may appear afterperspiration dries up. In addition, the disease causes respiratory disorderswhich can be both debilitating and lethal. It occurs in individuals homozygousfor recessive gene. If 2 normal parents had a daughter with the symptoms ofthis disease, and a normal son, what is the probability that he might be acarrier of the recessive gene?Express answer in fraction form.
The X-linked gene responsible for DMD encodes a protein called dystrophin that is required for muscle function. Dystrophin protein is not secreted—it remains inthe cells that produce it. Given what you know aboutBarr body formation, do you think that females heterozygous for the recessive DMD disease allele could havethe disease in some parts of their bodies and not others?
Clubfoot is a common congenital birth defect. This defect is caused by a number of genes but appears to be phenotypically distributed in a noncontinuous fashion. Geneticists use the threshold model to explain the occurrence of this defect. Explain this model. Explain predisposition to the defect in an individual who has a genotypic liability above the threshold versus an individual who has a liability below the threshold.
• ____________ add DNA to a chromosome and causemutant phenotypes either by increasing gene dosage orby changing the regulation of genes near a breakpoint.
The genetic variability of the Giddings children started out asmutations that occurred thousands of years ago. Take haircolor: Our distant ancestors probably all had dark hair, its colorcontrolled by multiple genes located on several different chromosomes.The alleles that produced Tess’s blond hair originatedas mutations in genes that control the amount and type of hairpigment. Tess probably inherited only “pale hair” alleles of all ofthese genes, so for any given hair color gene, she has the samepale hair allele on both homologous chromosomes. Chris, on theother hand, inherited both dark and pale hair alleles for at leastsome of the genes, so his homologues have different alleles. Aswe will see in Chapter 11, in many cases one allele (in this case,the dark hair allele) overrides the effects of the other allele (thepale hair allele), so Chris has black hair. What combinations ofalleles might have been packaged in Tess’s eggs and Chris’ssperm, which would combine to produce their…
Suppose a maternal effect gene exists as a functional dominantallele and a nonfunctional recessive allele that causes a disorder.A mother with the disorder produces offspring that are all withoutthe disorder. Explain the genotype of the mother.
On rare occasions, an organism may have three copies of achromosome and therefore has three copies of the genes on thatchromosome (instead of the usual number of two copies). Forsuch a rare organism, the alleles for each gene usually segregateso that a gamete will contain one or two copies of the gene. Let’ssuppose that a rare pea plant has three copies of the chromosomethat carries the height gene. Its genotype is TTt. The plant is alsoheterozygous for the seed color gene, Yy, which is found on adifferent chromosome. With regard to both genes, how manytypes of gametes can this plant make, and in what proportions?(Assume that it is equally likely that a gamete will contain oneor two copies of the height gene.)
.Certain forms of human color blindness are inherited as X-linkedrecessive traits. Hemizygous males are color-blind, but heterozygous females are not. However, heterozygous females sometimeshave partial color blindness.A. Discuss why heterozygous females may have partial color blindness.B. Doctors identified an unusual case in which a heterozygousfemale was color-blind in her right eye but had normal colorvision in her left eye. Explain how this might have occurred.

Albinism is a condition in which pigmentation islacking. In humans, the result is white hair, nonpigmented skin, and pink eyes. The trait in humans iscaused by a recessive allele.
