Question
Chapter 24.3, Problem 2LO
Summary Introduction
To determine: The reason that horizontal gene transfer can complicate evolutionary hypotheses.
Introduction: The gene transfer between the bacteria takes place through the process of transformation. The naked DNA molecule is transferred from one bacterium that is resistant to ampicillin to the bacterium that is sensitive to ampicillin. As there is no other aid like a conjugation tuber or a phage particle, the genetic material transfers directly and brings about the transformation of the bacteria

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.
