Explanation of Solution
Adaptive radiation is an important concept in evolutionary biology. The adaptive radiation is one of the few processes that allow the divergence or convergence of two or more species. Adaptive radiation requires both allopatric and sympatric speciation along with adaptation to different habitats. Speciation mainly occurs allopatrically and leads to rising of species that colonize other islands producing multiple species per island.
To determine: The relationship between the sympatric speciation and character displacement.
Introduction: Evolution of organism results into various types of accumulations in the genes of an organism that enable an individual to adapt in the changing environment.

Explanation of Solution
Sympatric speciation also occurs during the course of multiple generation because of disruptive selection and can result in the population to contain individuals exhibiting two different phenotypes. The instantaneous sympatric speciation occurs when an individual born is reproductively isolated from all other members of its species. A mutation that would cause an individual to be different from other members of species result in pleiotropic effects and subsequently end in adaptive radiation.

- Linkage in common bean 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…arrow_forwardAlleles at the P locus control seed color.
