The molecules that are necessary for life, apart from water. Introduction: Molecules are formed by atoms, i.e., one atom is chemically bonded with another atom to form molecules. Based on the sizes and shapes, molecules are classified into two types: micromolecules and macromolecules. Micromolecules are smaller in size and consist of low molecular weight, whereas macromolecules are larger in size and consist of high molecular weight. In addition to water, there are four major organic molecules are essential to life namely carbohydrates, proteins, nucleic acid , and lipids. Organic molecules are mostly occupied by carbon and hydrogen are called hydrocarbons. Large organic molecules are formed by polymerization of smaller units called monomers.

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…
