What conditions are necessary for populations to remain in hardy-weinberg equilibrium

Large population

Random mating

No evolutionary mechanisms (mutations, genetic flow,, genetic drift, natural selection)

Explanation:

According to  Hardy-Weinberg model, allele frequence (or genotype frequencies) will remain constant through generations in the absence of disturbing factors, evolutionary mechanisms. Such constant population is in Hardy-Weinberg equilibrium (no evolving population). Factor that can disturb equilibrium of the population are nonrandom mating, mutations, gene flow, natural selection, genetic drift.

According to Hardy-Weinberg model:

p2+2pq+q2=1 (p+q=1)

p2 is the frequency of dominant homozygous genotype

2pq is is the frequency of heterozygous genotype

q2 is is the frequency of recessive homozygous genotype

There are five conditions that disrupt the Hardy-Weinberg equilibrium:

Natural selection

Mutation

Genetic drift

Migration (gene flow)

Nonrandom mating

Explanation:

The Hardy-Weinberg equilibrium was explored earlier in this lesson in relation to allele frequency and the number of genotypes and phenotypes. This equilibrium was developed by Godfrey Hardy and Wilhelm Weinberg completely independent of one another. The equilibrium states that if there are no external forces of evolution on a population, then the allele frequency of that population will never change. The individuals within a population would all look the same as each other.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
