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?
Two mothers give birth to sons at the same time at a busy urbanhospital. The son of mother 1 has hemophilia, a disease causedby an X-linked recessive allele. Neither parent has the disease.Mother 2 has a son without hemophilia, despite the fact thatthe father has hemophilia. Several years later, couple 1 suesthe hospital, claiming that these two newborns were swappedin the nursery following their birth. As a genetic counselor, youare called to testify. What information can you provide the juryconcerning the allegation?
Write the number of different kinds of phenotypes,excluding sex, you would see among a large numberof progeny from an F1 mating between individuals ofidentical genotype that are heterozygous for one ortwo genes (that is, Aa or Aa Bb) as indicated. No geneinteractions means that the phenotype determined byone gene is not influenced by the genotype of theother gene.a. One gene; A completely dominant to a.b. One gene; A and a codominant.c. One gene; A incompletely dominant to a.d. Two unlinked genes; no gene interactions; Acompletely dominant to a, and B completelydominant to b.e. Two genes, 10 m.u. apart; no gene interactions; Acompletely dominant to a, and B completely dominant to b.f. Two unlinked genes; no gene interactions; A anda codominant, and B incompletely dominant to b.g. Two genes, 10 m.u. apart; A completely dominantto a, and B completely dominant to b; and withrecessive epistasis between aa and the alleles ofgene B.h. Two unlinked duplicated genes (that is, A and Bperform…
a. The ability to taste the chemical phenylthiocarbamideis an autosomal dominant phenotype, and the inabilityto taste it is recessive. If a taster woman with a nontasterfather marries a taster man who in a previous marriagehad a nontaster daughter, what is the probability thattheir first child will be(1) A nontaster girl(2) A taster girl(3) A taster boyb. What is the probability that their first two childrenwill be tasters of either sex?
Each box represents a potential offspring. Notice that genotypically speaking, they are all the same. Theyare all heterozygous (genotype) which means their phenotype is dark coloration. So, there is 100% chanceof producing a dark eyed, heterozygous offspring. What if that offspring mated with a light eyedindividual? Can you make a Punnett Square for that?Write the Genotypes and Phenotypes of the parents on the left of the square. Complete the square, thenwrite the potential offspring’s genotypes and phenotypes on the right of the square. Parents: Offspring:Genotypes: phenotypes:  What are the genotypes of the resulting offspring? What are the phenotypes of the resulting offspring?
Doing genetic analysis it is determined that two parents are heterozygous for two separate unlinked recessive traits (i.e., both parents are heterozygous for both loci). Given this genetic information, what is the probability of their having a child which is homozygous recessive for both traits?
Write down symbols for the alleles. (These may be given in theproblem.) When represented by single letters, the dominantallele is uppercase and the recessive is lowercase.
The part that is missing is where the traits for things like colorblindness and hemophilia exist. This meansthat if you have XY chromosomes, you are missing alleles on one of the chromosomes. So whatever alleleis on your X is expressed regardless of if being dominant or recessive. These X-Linked Traits have a specialway to note the alleles.X-Linked alleles use X and Y as their base and then the allele that notates the trait is in the top, rightcorner. For instance: Phenotype(appearance) Genotype(alleles) XY with Hemophilia XhY XX withouth Hemophilia XHXh Notice that the female has two X’s so has 2 alleles. She is not a hemophiliac, but is carrying the trait.That means she can pass the trait to her offspring.Why don’t you cross those two parents here and find the outcome:Parents: Offspring: Genotypes:Phenotypes: Is there a chance of producing an XY offspring with hemophilia? Explain your answer Will…
In a particular human family, John and his motherboth have brachydactyly (a rare autosomal dominant allele causing short fingers). John’s father hasHuntington disease (another rare autosomal dominant allele). John’s wife is phenotypically normaland is pregnant. Two-thirds of people who inheritthe Huntington (HD) allele show symptoms by age50, and John is 50 and has no symptoms.Brachydactyly is 90% penetrant.a. What are the genotypes of John’s parents?b. What are the possible genotypes for John? Howlikely is John to have each of these genotypes?c. What is the probability the child will express bothbrachydactyly and Huntington disease by age 50 ifthe two genes are unlinked?d. How will your answer to part (c) change if insteadthese two loci are 20 m.u. apart?
Attached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.
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.
A woman who is heterozygous, Bb, has brown eyes; B (brown) isthe dominant allele, and b (blue) is recessive. One of her eyes,however, has a patch of blue color. Give three different explanationsfor how this might have occurred?
