Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from
forsale [732]

The event that results from mitosis but not from meiosis is: C) daughter cells that are identical to the parent cell.

Mitosis is the process of cell division where a parent cell divides to form two daughter cells. These cells have the same number of chromosomes as that of their parent and that is the reason why the process is also known by the name equational division.

Meiosis is the process where a cell divided into 4 daughter cells and they have half of the total number of chromosomes as that of their parent. Thus is why the process is also called reductional division. Meiosis does not occur in the somatic cells of the body but in the germ cells.

An error sometimes made by beginning biology students is called the "Adaptationist Fallacy" wherin a trait observed in a populat
aleksley [76]

Answer:

The Adaptationist Fallacy can prove very costly to biologist who are assuming it wrong according to the function in the environment. Let us have an example of the phenotype of wheat diploid breed that produces non-bearded grains variety, but we cannot assume it as a beneficial phenotype without further extensive research. After research, we came to know that there is also a major hexaploid bearded variety, that produces more number of grains. That's how, the Adaptationist Fallacy may prove fatal if we have assumed diploid as a major beneficial phenotype.
