Alleles that have more influence in determining traits are?
phenotype
Is industrial melanism is stabilizing selection?
No, that would be more of a directional selection. Phenotypic change from a minor variant phenotype, black in this case, to the majority phenotype due to the environmental selection pressure of pollution on the moth phenotype.
Is it more common to be Rh- or Rh plus?
Rh positive is more common than Rh negative. Approximately 85% of the population is Rh positive.
What is wild type trait?
The phenotype is the physical appearance of an organism. The wild type phenotype is the most common phenotype found in wild populations of that organism. Wild type genes work together to produce the wild type phenotype. Wild type is the standard of reference. Nonstandard phenotypes can be attributed to the action of one or more mutant genes. Descriptions can be reduced to deviations from the standard. The mutant gene responsible for a deviation becomes the center of attention. And a standard of reference minimizes the chance of mistakes in interpreting the results of breeding tests.
What do mutations cause in genotype and phenotype?
They cause changes or more technically alterations.
What factor determines whether a particular phenotype occurs more frequent than others in certain population?
Gene frequency
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?
Directional selection: favors the phenotype at one extreme of a trait's range, selecting against the opposite extreme.Stabilizing selection: favors the intermediate phenotype, selecting against the phenotypes at both extremes of the trait's range.Disruptive selection: favors phenotypes at both extremes, selecting against the intermediate phenotype of the trait's range.
What are alleles that have an effect on an organisms phenotype?
The presence of more than two alleles for a trait is known as probility. There might be one which is dormant and the others which are recessive.
Alleles that have more influence in determining traits are?
phenotype
What percentage of the US has freckles?
Approximately 5-10% of the population in the US has freckles. Freckles are more common in individuals with fair skin and red hair.
The phenotype frequency in a population changes after each generation Which would most likely be causing this?
Competition between organisms (Apex)
Is industrial melanism is stabilizing selection?
No, that would be more of a directional selection. Phenotypic change from a minor variant phenotype, black in this case, to the majority phenotype due to the environmental selection pressure of pollution on the moth phenotype.
There or more forms of a gene that code for a single trait are called?
phenotype
