The role of histone H1 in the structure of the eukaryotic chromosome. Introduction: The proteins which help in condensing the DNA (deoxyribonucleic acid) into chromatin in the nucleus are called histone proteins. These proteins are basic (or alkaline) in nature and are positively charged as they are mostly made up of lysine and arginine. Their positive nature strongly attracts the negatively charged DNA. This ionic interaction helps in the tight packaging of DNA around the histone proteins. The histone proteins play a major role in gene regulation. The histone proteins are of 5 types, namely H1, H2A, H2B, H3, and H4.

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…
