What types of individuals in a population are represented by the two ends of a bell curve?
The individuals with extreme variations of a trait.
What is the meaning of under population?
lacking the normal/average or required population density
Average number of individuals of the same species per unit of surface area at a given time is the?
population density
The graphs of the 3 types of selection and label the average and the extremes?
In stabilizing selection, the average phenotype is favored, leading to a reduction in extreme phenotypes. In directional selection, one extreme phenotype is favored, causing a shift in the average towards that extreme. In disruptive selection, both extreme phenotypes are favored over the average, leading to a bimodal distribution in the population.
What is the number of individuals in a population called?
The number of individuals in a population is called population size.
What is a population pattern?
A population pattern is shown on a map where people live, such as dense areas within the population. Other patterns could be specific themes, such as average income of the population.
Why might average sized spider be favored in a given environment?
Average-sized spiders might be favored in a given environment because of their combination of size and speed.
What resulted from a genetic variation that was favored by natural selection?
The genetic variation that was favored by natural selection led to the increased frequency of the advantageous trait in a population over time, resulting in adaptation to the environment. This can lead to improved survival and reproductive success for individuals carrying the advantageous variation.
What is the phenotype that is present in most individuals in nature?
The phenotype that is present in most individuals in nature is typically the wild type phenotype, which is the most common and often the ancestral form of a trait within a population. It is favored by natural selection due to its adaptability and overall fitness for survival in the environment.
What is phenotype frequency?
A ratio of individuals with a particular phenotype to the total number of individuals in the population. Individuals with certain phenotype --------------------------------------------------- (Over) Total # of individuals within the population The distribution of traits in a population
Compare and contrast stabilizing directional and disruptive selection?
Stabilizing selection favors the average phenotype and reduces genetic diversity by selecting against extreme traits. Directional selection favors individuals at one extreme of the phenotypic range, leading to a shift in the population's average phenotype. Disruptive selection favors individuals at both extremes of the phenotypic range, increasing genetic diversity within the population.
Federalists favored ratification of the Constitution because they?
Federalists favored the ratification of the Constitution because they believed that a strong central government was needed. The federalists were generally wealthy individuals, that were opposed to anarchy.
