When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.
The five requirements for a population to be in Hardy-Weinberg equilibrium are:
- Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
- Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
- No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
- No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
- Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.
Answer:
The answer is None of the above
Explanation:
The reason why is because there are three main parts of the hindbrain, which are ... Pons, Cerebellum, and last but not least the Medulla oblongata.
Answer: C
one grade level because they made up many groups of students
All cells have at least one strand of DNA. prokaryotic cells are single celled, plants have a cell wall and vacuoles, animal cells have a centrosome. smooth or: synthesize lipids, metabolized carbohydrates, store calciumrough or: has bound ribosomes, produces proteinsGolgi apparatus: flattened membrane sacs, modifies products of the ER manufacturers macromolecule sorts. lysosomes: membrane sac of hydrolytic enzymes, hydrolyzes proteins, mitochondria: power house of the cell, makes ATP and such chloroplasts: allows photosynthesis to be a thing
The full form of ISP is, Internet service provider (ISP), company that provides Internet connections and services to individuals and organizations. ISPs are all connected to each other through network access points, public network facilities on the Internet backbone.
