Question
Chapter 11, Problem 6RQ
Summary Introduction
To discuss:
Whether the traits of individuals in the pedigree showing are homozygous or heterozygous and the observation concluded from the pedigree.
Introduction:
The inheritance of traits shows patterns used for the prediction of the reappearance of the traits in the offspring. The patterns of inheritance classified based on their relation to the autosomes or sex chromosomes and with dominant and recessive inheritance patterns.

Students have asked these similar questions
For this pedigree, give the most likely mode of inheritance, assuming that the trait is rare.
For the pedigree, what is the probability that III-4 and III-5 will have a boy AND he will be affected?
In pedigrees, individuals are usually specified by using a Roman numeral for their generation in the chart and an Arabic number for their position (reading left to right) within that generation. If we use the letter c for the allele that causes cystic fibrosis, what are the genotypes of individuals III-3 and III-4 (the third and fourth individuals shown in generation III) in the pedigree that shows this disease?
The pedigree below shows a family with a history of an autosomal recessive genetic
disease with one individual's genotype indicated (G denotes the normal allele and g
denotes the disease-causing allele).

Individual 1's father is known to be heterozygous (*) and his mother is known to be
homozygous dominant. Other individuals in the pedigree may be carriers, but are not
marked. The question mark (?) indicates that you do not yet know anything about this
individual's phenotype with regard to the disease.
Part 1
What is the probability that individuals 1 and 2 will have a child (5) who is a male with the
disease (the child is unborn and the sex is not yet known)?

- The three genes X, Y, and Z are linked on an autosomal chromosome in humans (X to Y is 15 cM, and Y to Z is 18 cM). If an individual that is heterozygous at all three loci (XYZ/xyz) has children with an individual that is homozygous recessive at all three loci (xyz/xyz), what is the probability that they will have a child that is phenotypically identical to either parent (X-Y-Z- or xxyyzz)? Assume there is no genetic interference to double crossover events at this site.arrow_forwardThe accompanying pedigree shows a family in which one child (II-1) has an autosomal recessive condition. On the basis of this fact alone, provide the following information.   1) What is the chance that among the three children in generation II who have the dominant phenotype, one of them is AAAA and two of them are AaAa? (Hint: Consider all possible orders of genotypes.) Express your answer to two decimal places.arrow_forwardGiven the following pedigree: Is the trait autosomal or sex-linked?

Remember, to produce the F2 generation you want to cross Heterozygotes from the F1. d) Genes 1 and 2 exhibit Epistasis (9:6:1) and Gene 3 is an Autosomal Dominant. In the P generation, the Male is Homozygous Recessive for the Genes showing Epistasis. Use E1, E2 and E3 to represent the Phenotypes shown by Epistasis. Report your results in the following format: P = aabb x AABB, F1 = 100%AaBb (Phenotype), and %3!
