Regarding Mendelian inheritance in diploid individuals, (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) a diploid individual receives two copies of every autosome from the previous generation. for every autosomal gene inherited by an individual, both copies can come from one parent. a diploid individual gives two copies of every autosome to a child in the next generation. U to be diploid means that two independent genes are specified in the individual's genotype.

Familial retinoblastoma, a rare autosomal dominant defect, arose in a large family that had no prior history of the disease. Consider the following pedigree (the darkly colored symbols represent affected individuals): a. Circle the individual(s) in which the mutation most likely occurred. b. Is the person who is the source of the mutation affected by retinoblastoma? Justify your answer. c. Assuming that the mutant allele is fully penetrant, what is the chance that an affected individual will have an affected child?
In the following pedigree, is the disorder’s mode of inheritanceautosomal dominant, autosomal recessive, or X-linked recessive?Explain your reasoning.
Ectrodactyly is a rare condition in which the fingers are absent and the hand is split. This condition is usually inherited as an autosomal dominant trait. Ademar Freire-Maia reported the appearance of ectrodactyly in a family in São Paulo, Brazil, whose pedigree is shown here. Is this pedigree consistent with autosomal dominant inheritance? If not, what mode of inheritance is most likely? Explain your reasoning.
The following pedigree shows the inheritance of Huntington’s disease, a fatal genetic disorder that causes neurodegeneration. Since signs and symptoms usually do not appear until adulthood, many who are carriers may not realize their risk of passing on the disease-causing allele. The following pedigree represents a family in which some people are affected by Huntington’s disease. Using just the information on this pedigree, is Huntington’s disease caused by a dominant allele or recessive alleles? What are the genotypes of the grandparents (I-1 and I-2)? What are the genotypes of the parents (II-6 and II-7)? If the parents above have another child, what is the chance that they will be affected by the Hungtington’s disease allele? What are the genotypes of the unaffected children (III-8, 9, 10)? What is the chance that the unaffected children above will pass on a Huntington’s disease allele to their children? What is the genotype of the affected child (III-11)? What is the chance…
Acatalasia is caused by a rare autosomal recessive gene. In heterozygous condition catalase activity is decreased slightly. A woman with a normal catalase activity have a husband with low catalase activity. What is the probability of children birth without anomaly in the family, if grandparents from both sides have reduced activity of catalase? Diagram the cross and mention the genotypes of all individuals in the family?
Which mode of inheritance is suggested by the following pedigree? Based on this hypothesis, and assuming that the trait is rare and has complete penetrance, what are the possible genotypes of all individuals in this pedigree?
Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons would be colorblind. Note that this is not a correct answer; it is just to give you an idea of how to explain the correct phenotypes of the cross.)___
What is the most likely pattern of inheritance for this disorder? (Is it autosomal dominant? Autosomal recessive? X-linked dominant? X-linked recessive? Y-linked? Mitochondrial?) Please include two specific pieces of evidence, present within the pedigree, that indicate that this pattern is most likely, as opposed to any other potential pattern. You may assume that the gene responsible for the trait is fully penetrant.
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?
The following pedigree shows what type of inheritance?
.a. Mutations in gene “X” are responsible for breast cancer and can be inherited into the next progeny. In one such case, one affected male parent (a father) who had only one affected parent (can be either male or female) too came to a genetic counselor. Upon the testing recommended by the counselor, it has been found that that male parent’s child has a 50% risk of developing the cancer. Can you discuss the inheritance pattern of this disease for this male parent? In which Mendelian disorder, all the children of a mother (both of her alleles of a gene on X chromosome are pathogenic) could also be affected?
The following pedigree illustrates the inheritance of a rare neurologicaldisease. What is the most likely mode of inheritance for this disorder?Explain your reasoning.
