a.
To determine:
The genotype of the parental type sperm John could produce in the given cross.
Introduction:
The set of genes in our DNA that is responsible for a certain trait is termed as the genotype. If the two organisms have even the slightest difference, their gene will have different genotypes.
b.
To determine:
The genotype of the recombinant type sperm produced by John.
Introduction:
The genetic makeup of an organism is termed as the genotype. It describes a complete set of genes of an organism.
c.
To determine:
Whether the B and D loci are linked or assort independently.
Introduction:
According to Gregor Mendel’s law of independent assortment, when two or more traits are inherited, the alleles for separate traits are transmitted to the next generation independent of each other. The assortment of one allele does not affect the selection of the other trait. When two genes are linked, they tend to be inherited together. When two genes are located on the same chromosome or occur very close to each other are said to be linked.

- Groodies are useful (but fictional) haploid organisms that are pure genetic tools. A wild-type groody has a fat body, a long tail, and flagella. Mutant lines are known that have thin bodies, are tailless, or do not have flagella. Groodies can mate with one another (although they are so shy that we do not know how) and produce recombinants. A wild-type groody mates with a thin-bodied groody lacking both tail and flagella. The 1000 baby groodies produced are classified as shown in theillustration here. Assign genotypes, and map the three genes. (Problem 25 is from Burton S. Guttman.)arrow_forwardRecombination frequencies between four genetically-linked loci in corn are shown in the following table: Loci Recombination Frequency (%) R and Q 45 W and Q 60 R and W 15 Q and L 10 L and R 35 What is the order of the genes on the chromosome?

Note that you need to know that the sequence of amino acids directly reflects the sequence of genes that coded for their placement. Homologous sets of genes ABCDEF and aBCdEF are located on - vnonhomologous chromosomes. Crossing over between them is suppressed because their locations are the result of this. Homologous sets of genes ABCDEF and AEDCBF are located on homologous chromosomes. A small region of a protein from three species is sequenced and found to be as follows: species X is alanine, glycine, glycine, threonine, alanine v species Y is alanine, glycine, threonine, alanine species Z is alanine, glycine, glycine, threonine, alanine The difference in the amino acid sequence of species Y is most likely due to this. a.

- In an in situ hybridization experiment, a certain clonebound to only the X chromosome in a boy with no diseasesymptoms. However, in a boy with Duchenne musculardystrophy (X-linked recessive disease), it bound to theX chromosome and to an autosome. Explain. Could thisclone be useful in isolating the gene for Duchenne muscular dystrophy?arrow_forwardAlleles of genes A and B were analyzed in Neurospora according to the cross shown below. Ordered tetrads are summarized in each horizontal row with the number of tetrads in each category listed alongside. A) Analyze the data to determine the recombination frequency (RF) between A and B, along with any additional information that is available from this data. B) Draw a map of the chromosome or chromosomes with appropriate map distances. C) Use the Perkins formula to reanalyze any relationship between A and B.arrow_forwardYou are studying four linked genes located on chromosome 2 in the fruit fly Drosophila melanogaster: adp (which contributes to obesity), b (which contributes to body color), pr (which contributes to metabolism), and vg (which contributes to wing formation). A series of crosses between pair-wise combinations of these mutations yielded the following recombination frequencies between the indicated loci: pr and adp 9% adp and b 6% pr and b 3% vg and b 10% vg and pr 7% What is the genetic distance in map units (cM) between the adp and vg loci? 16 9 6 4arrow_forward
- Shown here is PCR-based analysis of mouse pups from an experiment designed to evaluate the phenotypic impact of the sex-reversed Y chromosome gene (SRY). Interpret the data shown here clearly, defining the importance of each mouse tested and interpreting the results. Which mouse (of the three shown) is likely transgenic for Sry? Explain.arrow_forwardConsider the following "pericentric" ("around the center") inversion. In one an individual, a simplified 8-gene sequence along one chromosome is 1234 5678 while a pericentric inversion occurred on their other homologous chromosome, resulting in the sequence 1265 4378 (the dot represents the centromere). Draw these homologous chromosomes lined up (as during crossing over, in Prophase l). If a crossover event occurred between gene locus 3 and 4 (slicing between them) on the original chromosome, what would the crossover products look like? What would be the "problem" with each of the chromosomes that result?arrow_forwardn corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of the corn plants (i.e the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male sterile lines sing the cardboard chips, simulate the crosses indicated below. Give the genotypes and phenotypes of the offsprings in each cross, and properly label the nucleus and the cytoplasm of each individual in the cross Legend male sterile cytoplasm Male fertile cytoplasm FF nucleus Ff nucleus ff nucleus A.

- a) Are the genes linked? Please explain SPECIFICALLY how you can distinguish between linked and unlinked genes in this instance. b) If the two genes are linked, calculate the % recombination between ser and thr. Show the formula used, as well as all of your calculations. c) Draw a single map illustrating the arrangement of the two genes on the chromosome with respect to each other and to the centromere of the chromosome. Make sure to map ALL three distances.arrow_forwardThe STR DNA marker DS11 is located on the p arm of the chromosome #8 in humans. Molecular analysis has shown that Charlie Chaplin is a heterozygote for the STR marker (genotype DS11A and DS11B) Using this knowledge, provide a diagram of meiosis showing only the movements of chromosome 8 (assume no nondisjunction). Throughout, indicate where the marker may be found (in other words, label the chromosome to show where the STR markers can be found. (Show ONLY the chromosomes at interphase, metaphase 1, end of meiosis 1, metaphase 2, and end of meiosis 2). Suppose Charlie conceived a son with a chromosome 8 trisomy. Molecular analysis of the STR DS11 marker revealed that his son carried two copies of the DS11A marker and a DS11C marker. Based on the data, determine if the nondisjunction occurred in Charlie or in the mother? Provide your reasoning.arrow_forwardUsing figure 1 and the following background information answer the following questions. 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.
