The reason that mutations in genes encoding for DNA repair enzymes often produces a predisposition to cancer. Introduction: Mutation is a change in the sequence of genetic material either due to mistake in replication or due to changes in the environment. DNA enzymes have a property of proof reading which prevents any mistake in a nucleotide sequence, but sometimes due to few mistakes during DNA replication are undetectable. These alterations in the nucleotide sequences result in a mutation.

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…
