An allele responsible for Marfan syndrome Section 13.4 is inherited in an autosomal dominant pattern. What is the chance that a child will inherit the allele if one parent does not carry it and the other is heterozygous?
Pea plants have pods that are smooth (inflated) or constricted in shape and green or yellow incolor. These two autosomal traits observe the laws of Mendelian inheritance and assortindependently of one another. One gene affects pod shape and one gene affects pod color. Theallele for the smooth shape of pods (I) is dominant over the allele for the constricted shape ofpods (i) and the allele for the green color of pods (G) is dominant over the allele for the yellowcolor of pods (g).A pure breeding female parental pea plant with smooth green pods is cross-fertilized with a purebreeding parental male pea plant with constricted yellow pods. The resulting F1 generationplants are then self-fertilized and F2 generation progeny are obtained.The distribution of the appearance or phenotypes of the pods of the F2 generation plants are______.a- 100% smooth green podsb- 100% constricted yellow podsc- 50% smooth green pods, 50% constricted yellow pods, 0% smooth yellow pods, 0%constricted green podsd-…
Above is a pedigree for colorblindness. Based on the pedigree, is the disease dominant or recessive and is it sex-linked or autosomal? Why? Furthermore, what is the probability that 18 on this chart is affected but the condition, and what is the probability that 18 is a carrier? Why? Are the probability of being a carrier and an affected individual different? Why
Adenike and her partner, Debare, are expecting their first child. Adenike is healthy as are her two sisters but her brother has PKU, a recessive disorder of the PAH gene. Genotypically he must be pah-/pah-. Neither of Adenike's parents has PKU but both of her grandmothers did. Debare is a carrier of Sickle Cell trait, which means he has one allele for wildtype hemoglobin (HbA) and one allele for Sickle Cell (HbS), making him HgA/HbS. More importantly, he has two alleles for Marfan Syndrome, a pleiotropic dominant disorder that can affect up to 30 different traits (M+/M+). No one in Debare's family has ever had PKU and no one in Adenike’s family has ever had Sickle Cell or Marfan Syndrome. They consult a genetics counselor over concern of the health of their baby. The genetics counselor collects the medical histories of three generations; their grandparents, their parents, and them. In her calculations, she produces a phenotypic key that indicates M = Marfan, Hb = sickle cell, and pah-…

The following pedigree illustrates the inheritance of ringed hair, a condition in which each hair is differentiated into light and dark zones. What mode or modes of inheritance are possible for the ringed-hair trait in this family? 2 II 2 3 4 5 6 II 2 3 4 5 IV
Mendel’s observation that two different traits could be inherited independently of each other can be explained by understanding that: During meiosis, the process of chromosome assortment into daughter cells is random Alleles of the genes reside on homologous chromosomes All of the listed choices are correct During meiosis, maternal and paternal members of homologous chromosomes are distributed separately into daughter cells
Using the pedigree chart attached: Above is a pedigree for colorblindness. Based on the pedigree, is the disease dominant or recessive and is it sex-linked or autosomal? Why? Furthermore, what is the probability that 18 on this chart is affected but the condition, and what is the probability that 18 is a carrier? Why? Are the probability of being a carrier and an affected individual different? Why?
In the pedigree below what is the most likely mode of inheritance? Assume the phenotype of interest is rare. Group of answer choices 1 X-linked recessive 2 Mitochondrial 3 Autosomal recessive 4 X-linked dominant 5 Autosomal dominant 6 Y-linked
The pedigree shown below shows the inheritance of cystic fibrosis, a disorder that causes severe damage to the lungs and digestive system. Individual 5 shows no family history of cystic fibrosis and is considered to be homozygous for the normal allele. What is the probability that individual 10 is a carrier for the allele leading to cystic fibrosis?
(a) Enter the parent phenotypes and complete the Punnett square Inheritance of sex linked recessive tralts Example: Hemophilia Female paront phenotype Inheritance of hemophilia is sex linked. Males with the recessive (hemophilia) allele, are affected. Females can be carriers. (normal female) Xxh (carrier female) ben-N werxhxh (hemophiliac female) leizobXY (normal male) xhy (hemophiliac male) Male parent phenotype: Using the codes: XX eggs (a) Enter the parent phenotypes and complete the Punnett square for a cross between a normal male and a carrier female. sperm (b) Give the ratios for the phenotypes from this cross. Phenotype ratios: Inheritance of sex linked dominant traits Example: Sex linked form of rickets A rare form of rickets is inherited on the X chromosome.
