In each of the following pedigrees (C, D) by inspection, determine the mode of inheritance involved. Indicate the possible genotypes of all individuals in all the pedigrees.
For each of the following modes of inheritance, describe the features that will be exhibited in a pedigree in which the trait is present: autosomal recessive, autosomal dominant, X-linked recessive, X-linked dominant, and Y-linked inheritance.
Why is “threshold of liability” an important consideration in multifactorial inheritance?

- Does the phenotype indicated by the red circles and squares in this pedigree show an inheritance pattern that is autosomal dominant, autosomal recessive, or X-linked?arrow_forward—Hereditary canine spinal muscular atrophy (HCSMA) is a motor neuron disease in Brittany Spaniels. Breeding studuies within a kindred of more than 125 dogs (Brittany spaniel and beagle-Brittany outcrosses) have established an autosomal dominant inheritance for HCSMA. Which of the following genotypes would cause the dog to NOT HAVE HCSMA? Hh HH Hh A and C B and C– —(see question above for genotype) is a spaniel who is homozygous recessive for the HCSMA trait had a puppy with a spaniel who was heterozygous for this trait, what is the probability that the puppy would be normal? 0% 25% 50% 75% 100%arrow_forwardAcatalasia 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?arrow_forward
- There are several possible modes of inheritance through which traits can be inherited. The following pedigree charts represent four different inheritance patterns. Match each type of inheritance with the correct pedigree numbered above. (Use each number only once.)X-linked recessive X-linked dominant Autosomal recessive Autosomal dominantarrow_forwardWhat observation in a pedigree suggests a dominantpattern of inheritance?arrow_forwardIn a cross between an individual with Huntington disease and an unaffected individual, what are the chances their progeny will have the disease, considering that it is a dominant trait?arrow_forward
- Thalassemia is an inherited anemic disorder in humans. Affected individuals exhibit either a minor anemia or a major anemia. Assuming that only a single gene pair and two alleles are involved in the inheritance of these conditions, is thalassemia a dominant or recessive disorder?arrow_forwardWhat 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.arrow_forwardIs this pedigree dominant or recessive. Which best defines this pedigree Autosomal or sex-linked?arrow_forward
- In the cross between a female AaBbccDdee and male AabbCcDdee, what proportion of the progeny are expected to be phenotypically identical to the female parent?arrow_forwardChands syndrome is an autosomal recessive condition characterized by very curly hair, underdeveloped nails, and abnormally shaped eyelids. In the pedigree below: Which individuals must be carriers (heterozygotes)? ----- arrow_forwardRegarding 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. to be diploid means that two independent genes are specified in the individual's genotype.arrow_forward
