Background for Genetics Problems: In Mendel’s famous work with peas, he discovered that a variety of plant traits could be explained through inheritance of Information carried on discrete particles that were passed from parent to offspring. The information and particles were later described as genes (or, alleles) on chromosomes.
Background for Genetics Problems: In Mendel’s famous work with peas, he discovered that a variety of plant traits could be explained through inheritance of Information carried on discrete particles that were passed from parent to offspring. The information and particles were later described as genes (or, alleles) on chromosomes. Through his work and meticulous attention to details, Mendel was able to determine that the allele resulting in dwarf pea plants (dw) was recessive to the wildtype variety (+, tall) and that the constricted seedpod shape allele (cs) was recessive to a wildtype allele (+, inflated). Mendel’s extensive work with various crosses demonstrated that these characters assorted independently (meaning, they are not linked on the same chromosome). Part 1: DNA and Chromosomes Use a heterozygous pea plant (+/dw +/cs) to draw representations of cell nuclei at various stages in cell cycle using the table on the following page. In each drawing, label: +,dw, and cs alleles Homologous chromosomes Sister chromatids Centromeres For this problem, you may assume that there is a long sequence of bases for each gene and the alleles for each gene differ as follows. Use these in the construction of your answer for the middle column of the table. + allele: 3’ —- ATAAGC —- 5’ + allele: 3’ —- CTT —- 5’ dw allele: 3’ —-TTTACG —- 5’cs allele: 3’ —-CGA —- 5’ Mitosis: Life Cycle Phase Chromosome representation Double-Stranded DNA molecule (Base –pair sequences with 3’ and 5’ ends labeled) Summary Heterozygous pea plant cell at G1 *this cell is your “starting point” For the rest of the drawings Number of cells = n= Ploidy= DNA replicated or unreplicated state? G2 Number of Cells= n= Ploidy= DNA replicated or unreplicated State? Metaphase of Mitosis Number of Cells= n= Ploidy= DNA replicated or unreplicated State Daughter Cells (products of mitosis) Number of Cells= n=…

Average Score 50-85% |
40-38 points More depth/detail for the background and significance is needed, or the research detail is not clear. No search history information is provided. |
83-76 points Review of relevant theoretical literature is evident, but there is little integration of studies into concepts related to problem. Review is partially focused and organized. Supporting and opposing research are included. Summary of information presented is included. Conclusion may not contain a biblical integration. |
52-49 points Content is somewhat organized, but no structure is apparent. The use of font, color, graphics, effects, etc. is occasionally detracting to the presentation content. Length requirements may not be met. |

Poor Quality 0-45% |
37-1 points The background and/or significance are missing. No search history information is provided. |
75-1 points Review of relevant theoretical literature is evident, but there is no integration of studies into concepts related to problem. Review is partially focused and organized. Supporting and opposing research are not included in the summary of information presented. Conclusion does not contain a biblical integration. |
48-1 points There is no clear or logical organizational structure. No logical sequence is apparent. The use of font, color, graphics, effects etc. is often detracting to the presentation content. Length requirements may not be met |
