- 2. Null mutations are valuable genetic resources becausethey allow a researcher to determine what happens to anorganism in the complete absence of a particular protein. However, it is often not a trivial matter to determinewhether a mutation represents the null state of the gene.a. Geneticists sometimes use the following test forthe nullness of an allele in a diploid organism: If theabnormal phenotype seen in a homozygote for theallele is identical to that seen in a heterozygote(where one chromosome carries the allele in question and the homologous chromosome is known tobe completely deleted for the gene) then the alleleis null. What is the underlying rationale for thistest? What limitations might there be in interpreting such a result?2. Uniparental disomy is a rare phenomenon in whichonly one of the parents of a child with a recessivedisorder is a carrier for that trait; the other parent ishomozygous normal. By analyzing DNA polymorphisms, it is clear that the child received both mutantalleles from the carrier parent but did not receive anycopy of the gene from the other parent.a. Diagram at least two ways in which uniparentaldisomy could arise. (Hint: These mechanismsall require more than one error in cell division,explaining why uniparental disomy is so rare.)Is there any way to distinguish between thesemechanisms to explain any particular case ofuniparental disomy?2.

- Why is it more efficient to perform a test cross with a homozygous recessive donor than a homozygous dominant donor? How could the same information still he found with a homozygous dominant donor?1. The allele G for yellow stigma is completely dominant to green (g). Supposingtwo strains of autotetraploid plants are available and their genotypes are as follows:GGgg – in this plant the gene is close to the centromereGggg – in this plant the gene is far from the centromere If these two plants are crossed:a) provide the gametes that can be obtained from the two plants;b) provide the genotypic and phenotypic ratios of the offspring. 2. Consider the illustration below. Diagram the configuration you would observe at Anaphase I if crossing-over happens within the inversion. (IMAGE ATTACHED)1. 4. 6. Which mode(s) of inheritance could be RULED OUT for this smaller version of the previous pedigree? Does X-linked recessive fit the pattern? 5.
- 7. In rabbits, a locus involved in the control of coat colour may be occupied by any of fouralleles: Full colour (C), Sepia (ck), Cream (cd), or Albino (ca). A geneticist counted the numberof Full colour (C), Sepia (ck), Cream (cd) and Albino coat offspring resulting after crossesbetween Sepia (ck) and Cream (cd) coloured coated parents. The results were as follows.• Full colour (C): 152• Sepia (ck): 53• Cream (cd): 39• Albino (ca): 6Mendelian inheritance of this trait predicts that the ratio of Full colour (C) to Sepia (ck) to Cream(cd) to Albino (ca) should be 9:3:3:1. Do the experimental results support this mode ofinheritance?1. Given the karyotype shown here, is this a male or a female? What would the genotype/phenotype of this individual be?11. what is The statistic used to calculate the likelihood of genetic linkage between genes ?

With modern molecular methods it is now possibleto examine variants in DNA sequence from a verysmall amount of tissue like a hair follicle or even asingle sperm. (See the Fast Forward Box Mappingthe Crossovers that Generate the Chromosomes ofIndividual Human Sperm.) You can consider thesevariants to be alleles of a particular site on a chromosome (a locus; loci in plural). For example,AAAAAAA, AAACAAA, AAAGAAA, andAAATAAA at the same location (call it B) on homologous autosomes in different sperm might becalled alleles 1, 2, 3, and 4 of locus B (B1, B2, etc.).John’s genotype for two loci B and D is B1B3andD1D3. John’s father was B1B2and D1D4, while hismother was B3B3and D2D3.a. What is (are) the genotype(s) of the parental typesperm John could produce?b. What is (are) the genotype(s) of the recombinanttype sperm John could produce?c. In a sample of 100 sperm, 51 of John’s sperm werefound to be B1and D1, while the remaining 49 spermwere B3D3. Can you conclude whether the B and Dloci…4.
