How transposons could have led to selective advantages in organisms. Introduction: Transposons are genetic sequences that can more across the genome. That is why they are also called jumping genes. This leads to the change of nucleotide sequences that could result in mutation by translocation, insertion and deletions. This is why transposons hold a significant place in evolution of organisms.

Expert Solution & Answer

Explanation of Solution

The movement of transposons led to the change in the ORF (open reading frame). This could hinder the protein synthesis, thus acting as a regulator. At times it is possible this happened in an important gene and the organisms were affected adversely. On the other hand it is possible that a harmful gene was silenced.

For example: If a transposon got incorporated into the gene that codes for the colour of an insect with a red coat then the organisms will no longer be red. It is possible that the predators will not be able to find its prey as it no longer is coloured. As this insect survives, it will reproduce and spread its genes (natural selection). Thus, in this case transposons led to selective advantage in a species.

The numerous repeat sequences found in organisms are thought to have been the work of transposons. The corn kernel colour change is also attributed to the jumping genes.

Conclusion

Transposons change the nucleotide sequences at random. There are chances that these changes could lead to advantages in species and cause evolution.

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…
