Summary Introduction

To determine: The proper chromosomal constitution of a cell.

Introduction: Chromosome is a part of DNA that contains all genetic information. The chromosome is consisting of a packaging protein that binds with condense DNA molecules to prevent from the unmanageable problem.

Explanation of Solution

Cell division is an important event in which the division of parental cells leads to the two or more daughter cells. The cell division is taken place by mitosis and meiosis. Mitosis involves a single nuclear division after DNA replication. In mitosis, two daughter cell is produced, and a particular cell contains the original number of chromosome.

Whereas, meiosis involves two nuclear division without DNA replication and produces four daughter cells. Every daughter cells contain half of the original number of chromosomes because crossing over takes place in the prophase I of meiosis.

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…
