Question
Chapter 11.3, Problem 1CSC
Summary Introduction
To determine: Whether the pattern of inheritance that Mendel discovered also applies when there are several traits considered at once.
Introduction: “Marfan syndrome” is caused due to a mutation in the gene FBN1 that produces a protein called Fibrillin-1. This protein forms microfibrils inside the cells that support the connective tissues. The defect in this protein causes a lack of strength in the connective tissues of the human body. It is inherited in the form of the autosomal dominant trait.

Javid has two brothers. He looks a lot like one of them but not at all like the other one. All three have the same parents. How do Mendel’s laws of inheritance help us to explain this?
Mendel's Laws of Inheritance
Menders Success
Menders approach to the study of heredity was effective for several reasons. Foremost was his choice of experimental subject, the pea plant Pisum sativum.
Monohybrid Crosses
Mendel began by studying monohybrid crosses— those between parents that differed in a single characteristic.
The principle of segregation (Mendel's first law) states that each individual diploid organism possesses two alleles for any particular characteristic. These two alleles segregate (separate) when gametes are formed, and one allele goes into each gamete. Furthermore, the two alleles segregate into gametes in equal proportions.The concept of dominance that, when two different alleles are present in a genotype, only the trait of the dominant allele is observed in the phenotype.
Multiple-Loci Crosses
Dihybrid Crosses In addition to his work on monohybrid crosses, Mendel also crossed varieties of peas that differed in two characteristics (dihybrid crosses).…
Discuss how Mendel’s monohybrid results served as the basis for all but one of his postulates. Which postulate was not based on these results? Why?

- Neo-Mendelian Genetics: Complete dominance and overdominance Huntington’s disease, a neurodegenerative genetic disorder that typically becomes noticeable in middle age, is due to an autosomal dominant allele. Sickle cell anemia, on the other hand, is a genetic blood disorder due to a recessive allele. Mary is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Paul whose father died of Huntington’s disease. His mother, however, is not inflicted with that condition. Neither of his parents exhibits sickle cell anemia. What are the genotypes of Mary and Paul? If they plan to have four children, what is the probability that: all their children will be normal? ____________ they will have a son with Huntington’s disease? ___________ they will have a daughter inflicted with both conditions?____________arrow_forwardMendelian Genetics Hermione's parents are muggles (cannot perform magic).

Which trait is dominant?arrow_forwardThe “chestnut vs. black” debate Shortly after the rediscovery of Mendel’s pea plant experiments, biologists began investigating whether Mendel’s laws applied to other species, as well. In England, a debate broke out about whether the color of racehorses might be governed by Mendel’s laws. Using the British Jockey Club registry of racehorse pedigrees, biologists made the following observations: 1.A chestnut (red) stallion, when bred to chestnut mares, always produced chestnut foals. 2.Certain black stallions, when bred to chestnut mares, produced only black foals. 3.Other black stallions, when bred to chestnut mares, produced a mix of black foals and chestnut foals. Based on these observations, which is dominant: black or chestnut? 1st step: Test the two hypotheses described below. Draw the Punnett squares of the different combinations of parents (use the alleles C/c for color) one after the other, comparing your results with the observations described above. Hypothesis 1 = chestnut is…arrow_forward

- A family from coastal Africa recently moved to Canada. Soon after the move, their 6-month-old baby starts napping more frequently and often cries as if in pain. Concerned, the parents take their baby to a pediatrician, who diagnoses the baby with Sickle Cell Disease. The parents are astonished; neither has Sickle Cell Disease nor do their parents or siblings. How could this be possible? Use your knowledge of Mendelian Genetics and patterns of Inheritance to explain how this baby has Sickle Cell Disease when neither parent exhibits this disease phenotype. What term(s) could be used to describe the genotype of the baby's parents? What term(s) could be used to describe the genotype of the baby with Sickle Cell Disease?arrow_forwardTwo brown-eyed parents produce a blue-eyed child. Grandparents suspect infidelity on the part of the mother since neither parent had blue eyes. Explain the Mendelian relationships. What type of inheritance is represented here?arrow_forwardMendel knew that some traits could be closely associated. Mendel said that those traits were essentially the same trait. Could Mendel be including traits that were very closely linked or that were due to the same genetic factor? Did he need to distinguish between these two possibilities in order to reject them as evidence for his Law of Independent Assortment? Why or why not?arrow_forward
- Mendel's lawarrow_forwardGregor Mendel’s basic principles of inheritance say that each trait is controlled by just one gene with just two alleles, and that each allele is clearly dominant or recessive to the other. However, we now know that many (if not most) traits are not actually inherited according to these rules. Name and describe two other (i.e., non-Mendelian) inheritance patterns, including how each one works, and a give specific example of an actual trait that follows each pattern.arrow_forwardSickle cell anemia is a human genetic disorder caused by an autosomal recessive allele.
