∙ 8y agoIn population genetics the frequency of individual alleles remain constant as long as alleles are neither selected for or against.
Phenotypic frequency varies based on the relative frequency of the various dominant and recessive alleles in the population.
Further, if selection is taking place phenotype will tend to change in the direction of the allele selected.
If the population is small enough there is also the factor of genetic drift, which can change phenotype in one direction within a few generations.
Populations are certainly being acted on and alleles selected whether they are obvious phenotypically...if these traits are linked with ones that are visually apparent the change will manifest phenotypically but the change occurs because of linkage to the selected trait as opposed to by selection for the phenotypically obvious one.
Some traits give an advantage.

Which one directly influences the phenotype?
Yes and the successful phenotype was made by a successful genotype which actually changes allele frequency in evolution.
Which is an example of genetic drift?
Allele frequencies change randomly each generation. APEX
How is chemical evolution and biological evolution the same?
Chemical evolution: the evolution of the elements (building blocks of matter) biological evolution: the small scale change in a population that can be passed from generation to generation Both of these are changes that occur to gradually create a new species or substance
What is the study of influence changes in a population's size?
population dynamics-Population dynamics is the study of the factors that influence these changes in a population's size
What can be harmful if it reduces the organisms chances for survival and reproduction?
There are 3 things that can be harmful if it reduces the organisms for survival and reproduction. The three things are changes in DNA, changes in phenotype and mutation .
What phenotype frequency in a population changes after each generation which would most likely be causing this?
Genetic drift, natural selection, and gene flow are factors that can cause changes in phenotype frequency within a population after each generation. These changes occur as a result of random chance events, differential survival and reproduction of individuals, and the introduction of new genetic material from outside sources, respectively.
The phenotype frequency in a population changes after each generation Which would most likely be causing this?
Competition between organisms (Apex)
What pertains to small measurable evolutionary changes within a population from generation to generation?
Microevolution refers to small measurable evolutionary changes within a population over successive generations. These changes can include variations in allele frequencies or traits within a population. It is different from macroevolution, which involves larger-scale changes such as the emergence of new species.
Why is a persons phenotype harder to predict than a phenotype?
Because peoples appearances changes as their body changes.
What kind of phenotype changes are the results of evolution?
Changes that are genetic

The example of the English peppered moth demonstrates what?
B) that a harmful phenotype may become an advantageous phenotype when the environment changes
