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.

the answer to you question is   jet streams

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
