Chapter 16, Problem 2CQ
Summary Introduction
To identify: The copies of the OCA2 gene that influences eye color in humans.
Introduction: A karyotype helps in the identification of number, form, and size of chromosomes present within an actively dividing cell. Scientists discovered that eukaryotic chromosomes occur in sets by studying the karyotype of various species. The cells are treated with drugs before studying or making a karyotype.

ARVC5 is a disorder characterized by the replacement of healthy heart tissue with fatty fibrous tissue. Recent research has discovered the
mutated gene that causes the disorder is on chromosome 3. People who have the mutation have a GCG triplet instead of the normal ACA triplet.

An STR on chromosome 5 is very closely linked to a gene involved in a dominant metabolism disorder (one one copy of the mutation causes the disease). There are four different alleles of the STR (Q, B, S, and L), each with different numbers of GATCTCG repeats. The S allele
has 2 repeats, the B allele has 7 repeats, the Q allele has 10 repeats, and the L allele has 5 repeats.
Part 1
Lane 1 of the gel shown below indicates the locations of PCR products corresponding to all four STR alleles when run together in one lane. DNA was loaded into the wells at the top of the gel.
Move the letter of each allele to its correct position at the left of Lane 1 to indicate where each allele runs on the gel.

- The figure below represents a two-generation pedigree representing the inheritance of hereditary deafness (HD), which, has been shown to be autosomal recessive. Below the pedigree (and aligned with each person in each generation) are Southern blot gels for two RFLP loci. The BamH1 RFLP locus has alleles of either 7 kb or 5 kb and the EcoRI RFLP locus gives either a 4 kb or 3 kb EcoRI fragment. a. Determine if HD is linked to either of these markers. b. If linkage is detected between HD and one of the RFLPs, are there any recombinant offspring that you can detect? c. If linkage is detected between HD and one of the RFLPs, what is the approximate map distance between the two?

- Microsatellites are currently exploited as markers for paternity testing. A sample paternity test is shown in the following table in which ten microsatellite markers were used to test samples from a mother, her child, and an alleged father. The name of the microsatellite locus is given in the left-hand column, and the genotype of each individual is recorded as the number of repeats he or she carries at that locus. For example, at locus D9S302, the mother carries 30 repeats on one of her chromosomes and 31 on the other. In cases where an individual carries the same number of repeats on both chromosomes, only a single number is recorded. (Some of the numbers are followed by a decimal point, for example, 20.2, to indicate a partial repeat in addition to the complete repeats.) Assuming that these markers are inherited in a simple Mendelian fashion, can the alleged father be excluded as the source of the sperm that produced the child? Why or why not? Explain.

Identification of the genetic cause of hornlessness in cattle has been the subject of intensive genetic and genomic research, culminating in the nomination of two different candidate neomutations on cattle chromosome 1 that are predicted to have arisen 500-1,000 years ago: a complex allele of Friesian origin (PF), an 80,128 base pair (bp) duplication (1909352–1989480 bp), and a second, simple allele of Celtic origin (PC) corresponding to a duplication of 212 bp (chromosome 1 positions 1705834–1706045) in place of a 10-bp deletion (1706051–1706060)We report the use of genome editing using transcription activator-like effector nucleases (TALENs) to introgress the putative PC POLLED allele into the genome of bovine embryo fibroblasts to try and produce a genotype identical to what is achievable using natural mating, but without the attendant genetic drag and admixture.

The RFLP is 2 map units from the gene for DMD. Consider the following pedigree and Southern blot using a probe that hybridizes to the RFLP. Which band/s is/are associated with DMD? What is the genotype for individuals 3 and 4? (Remember, this is an X linked disease, so use X’s and Y’s to denote). Individual 9 married a man who does NOT have muscular dystrophy, and she is pregnant. DMD is an X-linked trait. What is the probability for their child to have DMD? An amniocentesis is performed and it is determined that 9’s child in utero has only a 10 kb band that hybridizes to the same probe used above. What can you say about the child now?arrow_forward
