No, sexual selection is not a requirement for Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium describes a population in which allele frequencies remain constant over generations, given certain criteria are met. Sexual selection, on the other hand, refers to the differential reproductive success based on traits that are attractive to potential mates.
What else can I help you with?
Why is Hardy-Weinberg equilibrium?
The distribution of alleles does not change from one generation to the next
Is the human population evolving according to the Hardy-Weinberg principles?
Yes, humans are still evolving and have not met the hardy-weinberg equilibrium. Although, I do believe our rate of evolution has been slowed down. The hardy-weinberg theorem states that allele frequencies will not chance if there is a large population, mating opportunities are equal, no mutations occur, no migration occurs, and no natural selection occurs. We certainly do have a large population (exception to certain isolated tribes that have not been influenced). This has slowed evolution because chance effect of genetic is nullified. It is arguable to say mating opportunities are not always equal; we have a hierarchy in society where the rich are clearly separated from the average and poor. We all have a tendency to mate with each other. Also, our ability to reason (which seperates us from all other species) has allowed us to make a much more in depth analysis into what behavioral and physical traits we are attracted to in our mates (does not strike me as much different then sexual dimorphism). This implies sexual selection, which is a form of natural selection. Think of all the locations where mutations occur (during replication, transcription, and translation), it is very unreasonable to think that in the entire human population no type of mutation ever occurs. It also has been proven that a mutation occurs, in a large population, in one in every gamete. Therefore, microevolution is still occurring. The human race is obviously always migrating to different countries, and therefore are under different environmental pressures. A problem however is that we have gotten extremely good at altering our environment to our standards rather then adapting. Furthermore, it has been proven that a gene on chromosome 12 in Africans has 21 different variations (this is one amongst many differences in allele frequencies between different races). Therefore, if a North American, who only has 3 variations, mates with an African, then the allele frequency has changed and again the hardy-weinberg conditions are not met.
Why is phenotype variation necessary for natural selection and sexual selection?
Phenotype variation is necessary for natural selection and sexual selection because it provides the raw material for evolution to act upon. Variation allows for individuals within a population to have different traits, which may offer advantages in survival, reproduction, or mate selection. Without phenotype variation, there would be no diversity for natural selection and sexual selection to operate on, thereby limiting the potential for adaptation and species diversification.
What are the different types of selection or system of elimination?
I don't think there's a certain type as such. Selection and Elimination can be structured or random. Random is self-explanatory, structured, is based on the individual/the criterion, i.e. I will pick all the green and red Easter eggs out of a packet, etc.
Compare Natural selection and sexual selection by completing the table?
Natural Selection vs. Sexual Selection | Aspect | Natural Selection | Sexual Selection | |----------------------|------------------------------------------------|------------------------------------------------| | Definition | The process where organisms better adapted to their environment tend to survive and reproduce. | A form of selection arising from the preference of one sex for specific traits in the other sex. | | Mechanism | Driven by environmental factors and survival advantages. | Driven by mate choice and competition for mates. | | Examples | Camouflage, resistance to disease, and resource acquisition. | Bright plumage in birds, elaborate courtship behaviors, and antlers in male deer. | | Outcome | Increases overall fitness and adaptation of the population. | Enhances reproductive success, potentially at the cost of survival. |
What does Hardy-Weinberg equilibrium predict will happen to the population allele and genotype frequencies after 1 generation of random mating?
What all the ideal non-real conditions of the Hardy-Weinberg equilibrium predict; no evolution takes place. Mating is assortative, non-random in the real world and sexual selection is at work when assortative mating takes place, thus evolution.
Why is Hardy-Weinberg equilibrium?
The distribution of alleles does not change from one generation to the next
What kind of selections occurs in many birds when males that build strong nests help care for young are chosen by females as mates?
This is called, sexual selection.
Among peacocks the males with the brightest and showiest feathers are favored as mates by peahens what is this example of?
sexual selection
What is the difference between sexual and natural selection?
Natural selection is survival of the fittest, while sexual selection is a preference for a given trait made by the limiting sex. It is strangely, but usually in opposition to natural selection (E.G., male peacock's tail feathers that garner attention from predators and prevent the peacock from fleeing well).
How does selective mating break h-w assumptions?
Assortative mating. Hardy-Weinberg condition, which are never met in the wild, posit random mating. We know that sexual selection does not tolerate random mating and female choice is a great driver of selective change in most organisms.
How does the process of natural selection differ from sexual selection in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms that drive evolution, but they differ in how they shape species. Natural selection is based on survival and reproduction, where individuals with advantageous traits are more likely to survive and pass on their genes. Sexual selection, on the other hand, is based on traits that increase an individual's chances of mating, such as elaborate displays or physical characteristics. While natural selection focuses on survival, sexual selection focuses on reproductive success and mate choice.

How has God made a peacock special?
Natural Selection and Sexual Selection has made a peacock 'special'.
Which condition may result in speciation?
Sexual Selection.
How do natural selection and sexual selection differ in their roles in shaping the evolution of species?
Natural selection and sexual selection are both mechanisms of evolution, but they differ in how they shape species. Natural selection acts on traits that affect an organism's survival and ability to reproduce in its environment, leading to adaptations that increase survival and reproduction. Sexual selection, on the other hand, acts on traits that affect an organism's ability to attract mates and reproduce, leading to the development of traits that enhance mating success. In summary, natural selection primarily influences survival and reproductive success in the environment, while sexual selection primarily influences mating success and reproductive opportunities.
