- 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?A dihybrid cross is performed between two heterozygous individuals (heterozygous for two traits). The resulting offspring had 62 individuals that were dominant for trait 1 and 2 (D/D), 7 individuals that were R/R, 21 individuals that were R/D, and 25 individuals that were D/R. Using Mendelian inheritance as the null hypothesis, use χ2 analysis to determine if the trait follows Mendelian inheritance. A. How many D/D phenotype offspring are expected? B. How many R/D phenotype offspring are expected? C. How many degrees of freedom are there? D. What is your calculated χ2 value? E. What is the critical value if using a probability of 0.05? F. Does the trait follow Mendelian inheritance?A cross like this (between two individuals heterozygous for two traits) is often referred to as a "two-point test cross". The expected ratio of phenotypes if the two traits are caused by unlinked genes displaying simple Mendelian dominant inheritance is 9:3:3:1. For this ratio, match each term of the ratio with the appropriate phenotype Wrinkled and green peas 1. 9 Round and yellow peas 2. 3 Round and green peas 3. 1 Wrinkled and yellow peas > >
- In the previous topic, you learned that Gregor Mendel used Pisum sativum to conceptualize the governing laws of Genetics. In this activity, we will recall how Gregor Mendel utilized the idea of classical breeding to come up with desirable traits. Supposed you have two individual peas. One of the peas is a pure breed with round green seeds while the other has heterozygous round yellow seeds. Supposed a farmer wants to have pure breed peas that have green wrinkled seeds. How are you going to come up with these traits using the two peas that you have? (Note: If the F1 does not include a pure breed green wrinkled seed, you will use the F1 peas for next generation breeding and so on until you have the desired traits. Pure breed means homozygous alleles.) Show the Punnett squares for the cross. You will come up with two or more squares based on how many generations you made.On the basis of Mendel’s observations (i.e. Mendelian patterns), predict the results from the following crosses with peas. Show the results in terms of genotypes, phenotypes, and their proportions in the offspring. The progeny of a tall (dominant and homozygous) variety crossed with a dwarf variety. The progeny of (a) self-fertilized. The progeny from (a) crossed with the original tall parent. The progeny of (a) crossed with the original dwarf parent.Mendelian Genetics Consider blue eyes in a man as recessive to brown eyes. Show the expected children of a marriage between a blue-eyed woman and brown-eyed man who had a blue-eyed mother. Determine the genotypic ratio (GR) and phenotypic ratio (PR) of the F1 using Punnett Square Method. Hint: Determine the genotypes of each individual first.
- What could be the genotypic and phenotypic ratios for a typical mendelian trait showed in the picture?Why are genetic variants with large effects on traits generally rarer than those with smaller effects? Explain how this relates to the observation that the heritability of common diseases is driven by common variantsGiven the pedigree for the trait A (with alleles A and a following mendelian genetics) below: What is the genotype of invididual I-1?
- A 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?B B BB Bb b Bb bb Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. If two brown rabbits, with the genotypes seen in the Punnett square above, have baby rabbits, what is the probability that the baby rabbits will also be brown? A B) 50% 75% D) 100% 5) According to Mendel's is why gametes have half the usual number of chromosomes. one copy of a gene is passed randomly from each parent to their offspring. This Sign out acerPigeons have long been the subject of genetic studies. Indeed, Charles Darwin bred pigeons in the hope of unraveling the principles of heredity but was unsuccessful. A series of genetic investigations in the early 1900s worked out the hereditary basis of color variation in these birds. W. R. Horlancher was interested in the genetic basis of kiteness, a color pattern that consists of a mixture of red and black stippling of the feathers. He carried out the following crosses to investigate the genetic relation of kiteness to black and red feather color (W. R. Horlancher. 1930. Genetics 15:312–346). Cross Offspring kitey × kitey 16 kitey, 5 black, 3 red kitey × black 6 kitey, 7 black red × kitey 18 red, 9 kitey, 6 black a. On the basis of these results, propose a hypothesis to explain the inheritance of kitey, black, and red feather color in pigeons. (Hint: Assume that two loci are involved and some type of epistasis occurs.) b. For each of the preceding crosses, test your hypothesis by…
