What causes variation within a species?
It has adaptations
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
What is phenotypic variation?
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
Discuss how 1 variation within a species 2 geographically isolated populations and 3 fossil organisms make it difficult to clearly define a species?
what is this, your homework? yes and its hard.
What did Darwin assert in his book On The Origin of Species as the mechanism of evolution?
Due to genes and mutations, organisms show variation within a species. Changes in the environment can put a selective pressure on the species - certain mutations may be more beneficial, therefore more individuals with that mutation will exist, as they survive and breed. This process is called Natural Selection.
What are specific examples of variation within a species?
Human species, as in the variation in height.
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.
Is mango leaf a parallel variation?
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the 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.
What causes variation within a species?

Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
What is the adaptive value of the process of crossing over as a source of variation in a species?
The process of crossing over during meiosis increases genetic variation within a species by shuffling genetic material between homologous chromosomes. This genetic diversity enhances the ability of a species to adapt to changing environments and increases the likelihood of beneficial traits being passed on to offspring. Ultimately, this can improve the species' chances for survival and successful reproduction.
What word is used to describe the differences of a species?
The word used to describe the differences within a species is "variation." Variation refers to the genetic, phenotypic, or behavioral differences among individuals of the same species, which can arise due to genetic mutations, environmental factors, or sexual reproduction. These variations are essential for the process of natural selection and evolution.
What does species all have genetic variation?
Genetic variation within a species refers to the differences in DNA among individuals, which can arise from mutations, gene flow, and sexual reproduction. This variation is crucial for a species' adaptability and survival, as it enables populations to respond to environmental changes, resist diseases, and avoid inbreeding. Moreover, genetic diversity can enhance resilience, allowing species to thrive in diverse habitats and under varying conditions. Overall, genetic variation is fundamental to the process of evolution and the long-term viability of species.
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.
Which process produces many variation in phenotype?
The process that produces many variations in phenotype is genetic recombination during sexual reproduction. This occurs when homologous chromosomes exchange genetic material during meiosis, leading to new combinations of alleles. Additionally, mutations and environmental influences can further contribute to phenotypic variation within a population. Together, these factors enhance genetic diversity and adaptability.
