What can mutations be a source of?
Mutations create changes in the genetic code. There are different types of mutations and vary in degree of harm or even benefit to the organism. If the mutation happens to be beneficial to the organism, then it can be passed down to its offspring and thus this leads to genetic variation in the population.
What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What is the ultimate source of variation needed for evolutionary change?
mutation
What effect does mutations have on variation?
Mutations are a source of genetic variation as they introduce new alleles into a population. They can lead to differences in physical characteristics, behavior, or susceptibility to diseases within a species. Over time, mutations can contribute to evolution by providing the raw material for natural selection to act upon, ultimately driving changes in a population.
Why are mutations considered a source of heritable variation in organisms?
Mutations are considered a source of heritable variation in organisms because they are changes in the DNA sequence that can be passed down from one generation to the next. These changes can lead to differences in traits and characteristics, allowing for genetic diversity within a population.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What is the source of genetic variation that refers to random error in the genetic code?
Mutations
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
What is a source of genetic variation that refers to a random error in the genetic code?
Mutations involve changes in the DNA code.

Is a source of genetic variation that refers to a random error in the genetic code?
A genetic mutation is a source of genetic variation that refers to a random error in the genetic code. Mutations can occur spontaneously during DNA replication, as a result of environmental factors, or due to mistakes in cellular processes. These mutations can lead to changes in the DNA sequence, potentially resulting in genetic variation within a population.

What is the primary original source of genetic variation in a population?
The primary original source of genetic variation in a population is mutation. Mutations are changes in the DNA sequence that can lead to new genetic variations in populations, providing the raw material for evolution to occur.

What is the source of genetic variation?
Genetic variation arises from mutations, genetic recombination during meiosis, and gene flow between populations. Mutations are changes in the DNA sequence, while genetic recombination mixes genetic material from two parents during sexual reproduction. Gene flow occurs when individuals migrate between populations, introducing new alleles into a gene pool.
