Chapter 12, Problem 17QP

The following family has a history of inherited breast cancer. Betty (grandmother) does not carry the gene. Don, her husband, does. Don’s mother and sister had breast cancer. One of Betty and Don’s daughters (Sarah) has breast cancer; the other (Karen) does not. Sarah’s daughters are in their 30s. Dawn, 33, has breast cancer; Debbie, 31, does not. Debbie is wondering if she will get the disease because she looks like her mother. Dawn is wondering if her 2-year-old daughter (Nicole) will get the disease.

  1.       a.            Draw a pedigree indicating affected individuals and identify all individuals.
  2.       b.            What is the most likely mode of inheritance of this trait?
  3.        c.            What are Don’s genotype and phenotype?
  4.       d.            What is the genotype of the unaffected women (Betty and Karen)?
  5.        e.            A genetic marker has been found that maps very close to the gene. Given the following marker data for chromosomes 4 and 17, which chromosome does this gene map to?

Imagine you are a botanist.  Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI).   Field Notes:  Specimen collected from shaded area along stream in South Cumberland State Park                 (Grundy County, TN). Laboratory Analysis:  Body:  Large leaves emerging from underground rhizome. Size: 63 cm  Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves:  Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History:  Diploid sporophyte dominant generation.  Haploid spores germinate into heart-shaped, haploid, gametophyte.  Water required for fertilization; no seed is produced.  Diploid zygote develops into sporophyte. Explain which domain, kingdom and phylum you believe this plant should be classified…
