Why is genetic diversity good for survival of a population?
The population will have more possible adaptations. a[ex just gave me the answer
What is the source of new traits in a population?
mutation
What is the definition of mainstream population?
people that share the same traits
What factors should be considered before comparing the frequency of traits in the classroom with their frequency in US population?
whether or not, ya mamma is fat
What is a region in which the people share one or more cultural traits?
A uniform area inhabited by people who have one or more cultural traits in common is called a formal region.
Selection favors one extreme form of a trait in a population.?
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
What selection favors organisms with phenotypes that are at one extreme rlative to the average phenotype?
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
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
Are all different types of traits the result of adaptation.explain?
No. You are describing what is called Lamarckism. Different traits are the results of the alleles found in genes. The environment does push one trait over another if the environment becomes extreme. You will see many traits in a population (such as in a human population) but one is not favored unless that trait allows those that have it to do better.
What removes individuals with average trait values creating two populations with extreme traits?
This is known as Directional Selection.
Why do population have variations in certain traits?
For one thing, different individuals have different alleles.
What each individuals within a population that have a unique combination of traits is called what?
Differential reproductive success
What is differential survival and reproduction among individuals of a population that vary in details of shared traits?
Natural Selection.
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
How evolution occurs via natural selection?
Evolution occurs via natural selection when certain traits become more favorable in a population over time. This is typically due to the environment or natural selection pressures in the population. Natural selection works by favoring individuals with traits that are better suited to the environment while those with less favorable traits may die off or be less likely to reproduce. Over time these favored traits become more common while unfavorable traits become less common. This process eventually leads to evolution as the population changes to adapt to its environment. The three main components of natural selection are: Variation: Individuals within a population have different traits Inheritance: Traits are passed from generation to generation Differential Reproduction: Traits that are more favorable are more likely to be passed onNatural selection is an ongoing process as the environment is constantly changing and influencing the traits of the population. It is important to note that natural selection is not a directed process and does not necessarily lead to a specific outcome. The result of natural selection is determined by the environment and the traits that are favored in the population.
Does inbreeding result in offspring that are heterozygous for most traits?
Inbreeding results in offspring that are homozygous for most traits - the variability tends to be bred out of the population.
What is the effect differential reproduction overtime?
Differential reproduction refers to the process where individuals with certain traits are more likely to survive and reproduce than others. Over time, this can lead to the accumulation of advantageous traits in a population through natural selection, driving evolutionary change. This can result in adaptations that are better suited to the environment, increasing the overall fitness of the population.
