disruptive selection.

What types od individuals in a population are represented by the two ends of a bell curve?

The individuals with extreme variations of a trait.


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.


Why are there 2 different variations of a trait?

Two different variations of a trait can arise due to genetic inheritance from both parents, where each parent contributes one version of the gene. Additionally, mutations can occur in the gene that leads to different variations of the trait. These variations can provide diversity within a population and may be beneficial in evolving to changing environments.


For each trait there are allele possibilities?

Yes, that is correct. Each trait is controlled by genes, and genes exist in different forms called alleles. For any given trait, an individual can have two allelesβ€”one inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.


When many genes contol a trait the trait will show a large number of what?

Variations


How does natural selection result in adaptation to the environment?

All organisms are variations and some of these variations confer survivability and reproductive success on the organism that processes the variant traits and the progeny of this organism and all against the immediate environment. Natural selection is just the immediate environment that selects these favored organisms over their conspecifics and then the progeny of these favored organisms leave greater allele frequencies of these favored traits in the populations gene pool and these trait grow to majority ststus as the adaption now seen in the population.


Which type of mutation is responsible for new variations of a trait?

matation in somatic


The different ways that a trait appears are called?

The different ways that a trait appears are called variations or manifestations of that trait. These variations can be influenced by genetic factors, environmental factors, or a combination of both.


What type of natural selection could have produced birds with these two extreme types of beaks?

The description of extreme beak types suggests disruptive selection, where individuals with either extreme of the trait are favored over the intermediate forms. This could occur if there are distinct ecological niches that benefit birds with specific beak shapes. Recommended: β‚•β‚œβ‚œβ‚šβ‚›://gβ‚’β‚œα΅£β‚’β‚šα΅’β‚›β‚—α΅’β‚˜.cβ‚’β‚˜/#ₐffβ‚Œα΅₯ᡒₖₐₛbₐbbₐᡣ₀₀₁


Is directional selection considered a random change?

Directional Selection is a more extreme form of the trait is favored. Ex. Flamingoes with longer legs and necks. Punctuated Equilibrium is sudden changes, then long periods without change- may be a combination of both.
