Pedigree shows a rare recessive disease. In generation III, which individuals are recombinant? parental? unknown?
Answer:
Fig: Pedigree given
Analysis:
For the pedigree analysis, first we have to label the pedigree with generation (in Roman) and number of Individuals.
Then try to find out the genetic composition of desired individual in specific generation.
Here, in the present pedigree, recombinant, parental and unknown individuals are as following:
Recombinant Individuals: 1, 2, 8, 9
Parental Individuals: 3, 4, 5
Unknown Individuals: 6, 7, 10
Conclusion:
In the present pedigree, which display a rare recessive disease, we can only find the individuals having recombinant, parental and some others which not clear the genotype.

Consider the following pedigree of a rare X-linked recessive disease. a) If individuals A and B have a child, what is the probability that the child will have the disease? b) If individuals C and D have a child, what is the probability that the child will have the disease? c) If the first child of C and D is normal, what is the probability that their second child will have the disease? d) If the first child of C...
Question 3 5 marks The following pedigree shows a family affected by a rare late-onset disease which is due to a mutation in a maternally imprinted gene. Individuals in generations I and II are all old enough to display the phenotype and all affected individuals are shown. Since this is a late onset disease, individuals in generation III are not yet old enough to display the phenotype, and therefore there are no affected individuals marked in this generation yet. The...
The mode of inheritance for the following pedigree is X-linked recessive. If individuals III-1 and III-2 were to have another child, what is the probability that they would express the trait? Explain your reasoning.
The pedigree shows the occurrence of a X linked recessive mendelian disease in a human family. Two unaffected family members were genotyped at a microsatellite locus and two different microsatellite alleles were observed (M1 and M2) I M1/M1 II 1 M1 M2 III 3 IV 3 5 a) Assume the disease and the microsatellite locus are completely linked. What is the genotype of individual IV-4 (give both disease and micrsatellite alleles in the genotype)? b) Assume that the disease locus...

What is the probability that the first child of IV-6 and V-3 would have Nance-Horan syndrome? Iv A) 114 B) 1/2 C) 1/8 D) 3/16 E) 3/4
22. In the pedigree shown below it has been found that the disease (indicated by the filled circles) is caused by a RARE autosomal recessive mutation in a gene that is paternally imprinted. What are the genotype(s) for individuals 1-2 and II-4, respectively? Imprinted alleles are identified with an asterisk. 1 II 6 성 모 . III 5 A) aa* and AA* B) aA* and Aa* C) aa* and Aa* D) Aa* and AA* E) aA* and AA*
Question 3 The following human pedigree shows a family affected by a specific disease. Assume that the individuals marked with an asterisk () do not carry any allele associated with the affected phenotype and that no other mutation spontaneously occurs. Also assume complete penetrance a) State the most likely mode of inheritance for this disease. Choose from: autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive b) Write all possible genotypes of the following individuals in the pedigree. Use the uppercase...
The pedigree below shows a family with a rare late-onset X-linked disease that is 8 m.u. from the STR locus R5T. The STR genotype is shown below each person. What is the probability II-1 will develop the disease later in life? 2,3 4 3 2,4 Select one: a. 8% b. 46% c. 92% d. O e. 4%
