Simple diffusion, if I’m reading your question right
Answer:
directional selection, stabilizing selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.
Answer:
dominant and recessive inheritance are useful concepts when it comes to predicting the probability of an individual inheriting certain phenotypes , especially genetic disorders . but the terms can be confusing when it comes to understanding how a gene specifies a trait . this confusion comes about in part because people observed dominant and recessive inheritance patterns before anyone knew anything about DNA and genes , or how genes code for proteins that specify traits .
