The two different extreme variation in a trait are favored in?
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.
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.
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.
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.
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 alleles—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
What is disputive selection?
Disruptive selection is a type of natural selection that favors extreme traits over the average trait, leading to the divergence of characteristics within a population. This process can result in the formation of two distinct phenotypic groups with reduced variation between them.
Different versions of the same gene are called?
Different versions of the same gene are called
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.
The different forms a gene may have for a trait?
Genes can have different forms, known as alleles, that produce variations in a specific trait. These alleles can be dominant or recessive, determining which form of the trait is expressed in an individual. Additionally, some alleles can be co-dominant or show incomplete dominance, leading to unique phenotypic outcomes.
What is most likely cause of directional selection?
The most likely cause of directional selection is a shift in environmental conditions that favors individuals with a particular extreme trait over others. This can lead to the gradual increase in frequency of that trait in a population over time.
