Was genetic basis for variations included in Darwins theory of evolution?

No. Darwin had no idea of what a gene was and did not even know that inheritance is particulate. He held with a " blending " idea called panspermia that was totally incorrect.
Mendel, by mathematical analysis, found that heritability was based on the particulate " factor. " Today we call these " factors " genes.

What is genetic evolution?
Genetic evolution refers to the variations in inherited traits of biological populations over successive generations. It is also referred to as the selfish gene theory.
Which is not part of darwins theory of natuarl selsction?
Random processes are not part of the theory of evolution by natural selection. Excepting random genetic mutation that provides the variation natural selection works on.
Mutations are important for evolution because they .?
Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.
Is both of sexual and asexual have genetic variations?
Yes, there will always be mutations.However, with sexual reproduction, there is a tendency for greater genetic variations.
Are adaptation genetic?
Yes, physical adaptions are genetic, it's called evolution.
Darwins theory of evolution did not contain the concept that?
Genetic variations are produced by mutations and sexual recombination

Which statement best explains the significance of meiosis in the process of evolution within species?
Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
Which two processes result in variations that commonly influence the evolution of sexual reproducing species?
mutation and genetic recombination.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.

What are the three measures to life's variations?
Adaptation: The ability to adjust to changing environmental conditions. Diversity: The range of different species and genetic variations within an ecosystem. Evolution: The process of natural selection and genetic change over time that leads to species' adaptation to their environment.
What is the relationship between genetic variations and mutations?
Mutations are random changes in DNA; genetic recombinations are new arrangements of genetic material (as a result of sexual reproduction). Together, they are the "fuel" that powers the "evolution machine," the direction of which is determined by natural selection.
What genetic change is always a result of evolution?
Evolution is not a cause of genetic change: it is the effect of genetic change.
What effects can mutations have on a virus?
They create genetic variations.
Is both of sexual and asexual have genetic variations?
Yes, there will always be mutations.However, with sexual reproduction, there is a tendency for greater genetic variations.
