Textbook Question
Chapter 9, Problem 14TYK
Adult height in humans is at least partially hereditary; tall parents tend to have tall children. But humans come in a range of sizes, not just tall and short. Which extension of Mendel’s model accounts for the hereditary variation in human height?

Why most of the genetic traits do NOT follow Mendel`s laws?
Two healthy parents have a child who is later diagnosed with cystic fibrosis.
What is the genetic term for this kind of disease?
Using Mendel’s pattern, pick a letter for this gene and give the genotypes of the parents
and the child.
What are the odds that their next child will also have cystic fibrosis?
Many traits that people think about as "running in families" or as being heritable in plants or animals are not inherited in the simple patterns that Mendel observed. What are some of the reasons that a trait could be strongly affected by genes but still not show the simple ratios that Mendel observed?

- A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?arrow_forwardThe following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?arrow_forwardWhat could be the genotypic and phenotypic ratios for a typical mendelian trait showed in the picture?arrow_forward
- What is the hypothesis that Mendel's laws are based on?arrow_forward. Which part of the pedigree in Figure 2-23 in your opinion best demonstrates Mendel’s first law?arrow_forwardIn the pedigree shown in Figure Q19–14, the first born in each of three generations is the only person affected by a dominant genetically inherited disease, D. your friend concludes that the first child born has a greater chance of inheriting the mutant D allele than do later children.A. According to Mendel’s laws, is this conclusion plausible?B. What is the probability of obtaining this result by chance?arrow_forward
- Why is not Mendel’s secondlaw always valid for two ormore phenotypical traits of anindividual?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_forwardIn pea plants, smooth peas is dominant to wrinkled peas. When Mendel crossed true breeding smooth peas with true breeding wrinkled peas, what is the genotype of the offspring and what percentage?arrow_forward
- According to Mendel’s law phenotypical characteristics would be determined by pair of factors (alleles) that separate independently in gametes. What are the main types of inheritances that are exceptions to Mendel’s rules?arrow_forwardWhat is Mendel’s secondlaw?arrow_forwardA woman with fair skin, blond hair, and blue eyes gives birth to fraternal twins; the father has dark brown skin, dark hair, and brown eyes. One twin has blond hair, brown eyes, and light skin, and the other has dark hair, brown eyes, and dark skin. What Mendelian law does this real-life case illustrate and explain what this means in terms of the inherited alleles for these genes?arrow_forward
