Summary Introduction

To analyze:

The effect of heat produced by the lights on the growth of bacteria in the Winogradsky column.

Introduction:

Winogradsky column is a device used for culturing diverse microorganisms. It illustrates how different species of microorganisms perform their roles and how one organism enables the growth of others. The column containing pond mud, water, and different gradients are kept under sunlight for months.

As a result, the growth of different species of microorganisms is found inside the column and they include desulfovibro, chromatium, and other species of bacteria, cyanobacteria, and algae.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
