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.
What are causes for mutations?
Differences in the genetic code that lead to advantages above other members of the species. Thus if it is a valued trait it will be passed on.
How do species get variation?
Species diversify via genetic mutations. Say organism A has 4 offspring, and they all have trait 1, which is characteristic of the species, except one baby, which has trait 2 (call this one organism B). Later on organism B has offspring which all have trait 2, and a couple other new traits that are uncharacteristic of the species. Eventually, the descendants of organism B will be so different from the descendants of organism B's siblings, that they could be considered a new species.
What correctly explains how a favorable genetic trait can increase in frequency in a population?
A favorable genetic trait can increase in frequency in a population through natural selection, where individuals with the trait have higher reproductive success. This allows them to pass on the trait to more offspring, leading to an increase in the trait's prevalence over time.
When considered a evolutionary favorable trait for the organism a trait must increase the individuals what?
chicken
What type of mutation is responsible of new variations of a trait?
A random mutation in the DNA sequence is responsible for new variations of a trait. These mutations can be caused by errors during DNA replication, exposure to mutagens or other external factors. The variations produced by mutations can contribute to genetic diversity within a population.

What is Favorable mutations?
A helpful change to someones body that not man people have.

The two different extreme variations in a trait are favored in?
The two extreme variations in a are trait are favored in disruptive selection.
When many genes contol a trait the trait will show a large number of what?
Variations
What could happen to DNA that would cause a change in trait or a new trait to be expressed?
That would be a mutation. There are several types of mutations such as silent, nonsense, missense mutations along with inserstions, deletions and amplifications
What are the different ways in which individuals with a particular trait may increase in a population?
different ways in which individuals with particular trait may increase are -if that particular trait provides them with some sort of support to undergo the circumstances they are found in, we can also call it natural selection -or due to any genetic drift, that is a natural calamity, also called a chance selection
The different ways that a trait appears are called?
it can be big or small, large or tiny. itdoesn't matter the size, shape, or color. its still the same as it was.
What role do mutations play in evolution?
They provide the variation in organisms that other recombination methods do not. A beneficial mutation, leading to a small change in same trait, that is even marginally reproductively successful to the organism that possesses it will be selected for and passed on tho progeny thus changing the organisms population over time, regardless of how small the change. This is evolution, change in populations over time.
Which type of mutation is responsible for new variations of a trait?
matation in somatic
