The term “genetic instability”. Introduction: Mutation is a change in the sequence of genetic material either due to the errors in DNA replication or due to the changes in the environment. Chromosomal mutations occur due to abnormality, aberrations, disorder or mutation in the segment of DNA leading to extra, irregular or missing portions of chromosomal DNA. Most tumors contain cells with “chromosomal mutation”.

Some ways in which genomic instability may arise.

Introduction:

Defects in the repair mechanism of DNA may also contribute to chromosomal rearrangement and genetic instability. Many repair system of DNA makes double and single-strand breaks in the DNA as a part of the mechanism. If these breaks are not repaired properly with time then they often result in a rearrangement of chromosomes and condition of genetic instability.

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…
