Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
What else can I help you with?
Why does natural selection does not act directly on genes?
The natural selection process is a gradual one and is found to pose a gradual effect on the genes because the nitrogenous base bonds in the genes are not an easy task to alter and the hydrogen bonds existing between these bases would change according to change in the environmental barriers that arise out of catastrophes to which the selection has to incur. So the gradual modification is found to be observed in the level of genes in case of natural selection in animals. This was the case for Galapogous island finches in case of Darwinian studies in natural selection. The genotype variations are the gradual ones leading to changes in the phenotype of the organisms.
When organisms carry genes that make them more likely to survive to reproduce the process called what occurs?
natural selection
What are some natural selection for deer?
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.
How does population change as a result of natural selection?
Natural selection is not a thing that acts on populations, it is a tendency for harmful genes to not be passed on (die out) and useful variations to thrive and become common.
The process that encourages the passage of benficial genes and discourages the passage of harmful or unfavorable genes from one generation to the next?
This process is known as natural selection, a key mechanism of evolution where individuals with beneficial traits that enhance survival and reproduction are more likely to pass on their genes to the next generation. Harmful or unfavorable genes may be selected against, reducing their frequency in the population over time.
Why does only traits controlled by genes be acted upon natural selection?
Traits controlled by genes are subject to natural selection because they are heritable and can be passed on to offspring, allowing successful variations to increase in frequency over generations. Traits that are not controlled by genes, such as behavior or learned characteristics, are not directly influenced by genetic inheritance and therefore cannot be directly acted upon by natural selection.
Natural Selection acts on the?
On the individual, or on his genes.

What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
When organisms carry genes that make them more likely to survive to reproduce the process called what occurs?
natural selection
Is it that traits that are controlled by genes can be acted upon by natural selection?
Yes.
What are some natural selection for deer?
Natural selection will see to it that genes from the strongest and more fertile bucks and does are passed down susequent generations.
What is being selected in natural selection?
The individual, or the genes of the individual. All organisms are variants in phenotype and behavior. So, natural selection is the immediate environment these organisms are in and those that survive and reproduce better in this environment leave more descendants which carry the genes that promoted that survival and reproduction advantage. Then those genes are more represented in the populations gene pool and this is evolution.
When a population is split into smaller groups. why do these groups develop different traits?
Evolutionary mechanism work on the two subgroups independentlyWhen a group is split forces like natural selection and genetic drift affect the genes of the two subgroups differently. Mutations that arise in one group are not passed to the other group through reproduction.
What are four forces that can change the frequency of genes in a population?
- natural selection - sexual selection - genetic drift - immigration/emagration
What is the process by which organisms with favorable genes are more likely to survive and reproduce?
natural selection
Is it true natural selection can act upon an individuals genotype the external of genes?
False
