Answer:
The correct answer is - The Dobzhansky-Muller Model.
Explanation:
The Dobzhansky- muller model is a model that explains about how the natural selection influences speciation or reproductive isolation in a specific process when hybridization takes place between 2 species of an organism.
The offspring that produce through this process is an incompatibility with other species of origin. In the given question, spotted platyfish that arise due to the X linked gene exhibits the Dobzhansky-muller model.
Thus, the correct answer is - The Dobzhansky-Muller Model.
The keratinocytes approximately 90% of cells.
Because you need your legs to carry your whole body, so, essentially, your legs have to have bigger bones and muscles.
Answer:
C.
Explanation:
The small population size means that the new colony may have reduced genetic variation from the original population and that variation, in this case, included the dominant allele for Huntington's disease. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution. In this case, it was a chance that the settlers all carried the allele for Huntington's disease.
