In a population a shift in the average population phenotype toward the mean an away from the physical extremes this process lowwers phenotype variety the ppulation is more homogeneous?
The process described is known as stabilizing selection, where individuals with average phenotypes have a higher fitness than those with extreme phenotypes. This leads to a reduction in phenotypic variation within the population, as traits that deviate from the mean are less likely to be passed on to future generations. Consequently, the population becomes more homogeneous, as the average phenotype becomes more prevalent. This can enhance the population's overall stability in a consistent environment but may reduce its ability to adapt to changing conditions.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
Is industrial melanism is stabilizing selection?
Industrial melanism is an example of directional selection, not stabilizing selection. In this phenomenon, environmental changes such as pollution cause a shift in the frequency of dark-colored individuals within a population, which increases their survival rates due to camouflage. Stabilizing selection, on the other hand, favors the intermediate phenotype, reducing the variation in a population.
Are dominant phenotypes more common?
Not necessarily. The frequency of a phenotype in a population is determined by a variety of factors including genetic drift, selection pressure, and mutation rates. Dominant traits do not automatically make a phenotype more common.
Evolution is the gradual change in phenotype frequency of a species what process causes evolution?
Evolution is primarily driven by natural selection, which occurs when heritable traits that provide an advantage for survival and reproduction become more common in a population over time. Other processes that can cause evolution include genetic drift, gene flow, and mutations. These processes interact to shape the genetic makeup of a population and lead to changes in phenotype frequency over generations.
What factor determines whether a particular phenotype occurs more frequent than others in certain population?
Gene frequency
What is the most common phenotype?
The most common phenotype in a population is usually determined by the dominant allele of a gene. This means that the trait associated with the dominant allele will be more prevalent compared to the recessive allele's trait. Additionally, environmental factors can also influence the prevalence of certain phenotypes in a population.
What term describes a population that has more than one phenotype for a particular trait?
polymorphic
Why natural selection acts on the phenotype rather than genotype?
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
How many warblers are left in the world?
There are many species, some more common than others. The total warbler population has to be in the millions.
Which religion is more population in India?
Hinduism. There are many types of religion in India. Islam and Christianity are the others. Hinduism is the most common.
What are the 3 ways natural selection can affect a population?
Natural selection changes the genetic makeup of a population by favoring some genotypes over others. It does so through the differential reproduction of those genotypes. Put simply, if I possess a variant of a trait (and the genotype underlying it) which allows me to leave behind more adult offspring than those with different variants of that trait, then my variant will become more common in the population than the others. The result is a change in the frequency of the gene variants: mine increases in frequency at the expense of the others. This change in the frequency of gene variants (known as alleles) over time in a population is the basic definition of evolution itself.
Recessive allele is more common or dominant allele?
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.

Why are some phycal traits more common than others?
Physical traits can be more common than others due to a variety of reasons, including natural selection, genetic variation, and environmental influences. Some traits may offer a survival advantage in certain environments, leading to their prevalence in a population. Additionally, traits with a strong genetic basis or that are determined by dominant alleles are more likely to be common.
Are dominant phenotypes more common?
Not necessarily. The frequency of a phenotype in a population is determined by a variety of factors including genetic drift, selection pressure, and mutation rates. Dominant traits do not automatically make a phenotype more common.
