Analysis of Autosomal Recessive and Dominant Traits Huntington disease is a rare, fatal disease that usually develops in the fourth or fifth decade of life. It is caused by a single autosomal dominant allele. A phenotypically normal man in his twenties who has a 2-year-old son of his own learns that his father has developed Huntington disease. What is the probability that he himself will develop the disease? What is the chance that his young son will eventually develop the disease?
A wild population of pea plants has two alleles for flower color in its gene pool. A dominant allele (P) specifies purple flowers; a recessive allele (p) specifies white flowers. If the die frequency of allele P is 0.75, what is the expected frequency of allele p?
Monozygotic (MZ) twins have a concordance value of 44% for a specific trait, whereas dizygotic twins have a concordance value of less than 5% for the same trait. What could explain why the value for MZ twins is significantly less than 100%?
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.

In sheep, the formation of horns is a sex-influenced trait; the allelethat results in horns is dominant in males and recessive in females.Females must be homozygous for the horned allele to have horns.A horned ram was crossed to a polled (unhorned) ewe, and the firstoffspring they produced was a horned ewe. What are the genotypesof the parents?

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…
. Consider the genotypes of two lines of chickens: thepure-line mottled Honduran is i/i ; D/D ; M/M ; W/W, andthe pure-line leghorn is I/I ; d/d ; m/m ; w/w, whereI = white feathers, i = colored feathersD = duplex comb, d = simplex combM = bearded, m = beardlessW = white skin, w = yellow skinThese four genes assort independently. Starting withthese two pure lines, what is the fastest and mostconvenient way of generating a pure line that has coloredfeathers, has a simplex comb, is beardless, and has yellowskin? Make sure that you showa. the breeding pedigree.b. the genotype of each animal represented.c. how many eggs to hatch in each cross, and why thisnumber.d. why your scheme is the fastest and the mostconvenient
After the rediscovery of Mendel’s principles of inheritance in the earlytwentieth century, eugenics became popular in many countries,including the United States. The eugenic movement proposed toimprove the human species through the application of genetics. Anumber of eugenic laws were passed, prohibiting the marriage ofpeople with certain conditions and allowing for the involuntarysterilization of others. Eventually this practice fell into disfavorbecause of ethical concerns and because many of the laws were basedon bad science. Some people think that the increasing use of moderngenetic techniques to test for genetic diseases and traits and tomanipulate reproductive outcomes representsthe resurgence of eugenics. What are some ethical concerns associatedwith encouraging the birth of people with desirable traits anddiscouraging the birth of those with undesirable traits?
Huntington disease is a rare fatal, degenerative neurological disease in which individuals start to showsymptoms in their 40s. It is caused by a dominant allele.
