A couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the womans family but not in the mans family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?
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.
Crossing Pea Plants: Mendels Study of Single Traits Sickle cell anemia (SCA) is a human genetic disorder caused by a recessive allele. A couple plan to marry and want to know the probability that they will have an affected child. With your knowledge of Mendelian inheritance, what can you tell them if (1) each has one affected parent and a parent with no family history of SCA or (2) the man is affected by the disorder but the woman has no family history of SCA?
Unattached earlobes (E) are dominant over attached earlobes (e) [Figure (a) and (b)]. If a woman with unattached earlobes and a man with attached earlobes have children, what percentage of their children has the possibility of having unattached earlobes if the mother is homozygous for the trait?
Having a widows peak is dominant W to not having one (ww)Having attached earlobes is a recessive trait (ee)- Jack and Jill are heterozygous for both traits.What's the probability of them having a child with a widow's peak and attachedearlobes?
A couple has three children, all of whom have brown eyes and blond hair. Both parents are heterozygous for brown eyes (Bb), but one is blond (rr) and the other is a redhead (Rr). What is the probability that the next child will be a brown-eyed redhead? For full credit, you must show all work
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…
Pisssssssss helppppppppp, I’m sorry I know this is kind of a lot. How can NF1 be spontaneous? Include the following terms: -genotype - phenotype - homozygous - heterozygous - inheritance - alleles - dominant - recessive
In humans, unattached earlobes (E) are dominant to attached earlobes (e). If a child is born with unattached earlobes, and a mother with attached earlobes, and a dad with unattached earlobes, what is genotype of the dad? O a. EE or Ee O b. ee O c. Ee O d. Ee or ee O e. EE

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?
