Chapter 4, Problem 1PDQ
HOW DO WE KNOW? In this chapter, we focused on extensions and modifications of Mendelian principles and ratios. In the process, we encountered many opportunities to consider how this information was acquired. On the basis of these discussions, what answers would you propose to the following fundamental questions?
- (a) How were early geneticists able to ascertain inheritance patterns that did not fit typical Mendelian ratios?
- (b) How did geneticists determine that inheritance of some
phenotypic characteristics involves the interactions of two or more gene pairs? How were they able to determine how many gene pairs were involved? - (c) How do we know that specific genes are located on the sex-determining chromosomes rather than on autosomes?
- (d) For genes whose expression seems to be tied to the sex of individuals, how do we know whether a gene is X-linked in contrast to exhibiting sex-limited or sex-influenced inheritance?

Hydrogen bonds play an important role in stabilizing and organizing biological macromolecules. Consider the four macromolecules discussed. Describe three examples where hydrogen bond formation affects the form or function of the macromolecule.
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.
