Variation is caused by a mutation to the base sequence of DNA. It can be good if it helps with survival. It is also to do with natural selection. For example, plants with bigger leaves can take in more sunlight and can make food easily.
So if some plants with a range of different leaf sizes e.g 2cm-8cm, are living near the bottom of a forest and then some other plant comes along and grows to be taller than the first plants and blocks off sunlight, the original plants with smaller leaves die off. They can't get enough sunlight to make food. Now there are bigger leaved plants growing near the bottom and when they reproduce the pass on their good, big leaved genes. So now there are more big leaved plants in the population.

What is the major cause of variation within species?
Genetic mutations are the major cause of variation within species. Mutations can introduce new genetic traits that can be passed on to offspring, leading to diversity within a population. Other factors like genetic recombination, migration, and environmental influences can also contribute to variation within species.
What is the correct term for variation in characteristics within populations of the same species A variation in characteristics within populations of the same species is called?
A variation in characteristics within populations of the same species is called intraspecific variation. This variation can occur due to genetic differences, environmental factors, and developmental processes, leading to diverse traits among individuals in the same species. Understanding intraspecific variation is crucial for studying evolution, ecology, and conservation.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
Why are there so much variation with a species?
Variation within a species is due to genetic diversity, which arises from random mutations, recombination during reproduction, and gene flow from other populations. This variation provides the raw material for natural selection and enables species to adapt to changing environments.
How does variation within a species contribute to the health of the species?
Variation within a species, often referred to as genetic diversity, enhances a population's ability to adapt to changing environments and resist diseases. This diversity allows for a greater range of traits that can improve survival and reproduction under different conditions. Additionally, it helps mitigate the risks associated with inbreeding, which can lead to increased vulnerability to threats. Overall, genetic variation is crucial for the resilience and long-term survival of a species.
Is adaptations a genetic basis for variation within a species?
No, adaptations usually do not result in any genotypical change in a species.
What is the major cause of variation within species?
Genetic mutations are the major cause of variation within species. Mutations can introduce new genetic traits that can be passed on to offspring, leading to diversity within a population. Other factors like genetic recombination, migration, and environmental influences can also contribute to variation within species.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
What is a major cause of variation within species?
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
How does variation within a species bring about evolutionary change need specific example that also mentions genetic variation and environmental conditions?
yes

What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population

What is the name given to the difference in characteristic between organism of the same species?
The difference in characteristics between organisms of the same species is called "genetic variation." This variation can arise from mutations, sexual reproduction, and environmental factors, leading to diversity in traits such as size, color, and behavior within the species. Genetic variation is essential for natural selection and the overall adaptability of populations.
