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 else can I help you with?
Does evolution happen on a genetic level?
Yes, evolution occurs on a genetic level through changes in the frequency of genetic variations over successive generations. These genetic variations can lead to changes in an organism's traits that can be passed on to offspring, driving evolution.
How do DNA mutations impact genetic diversity and evolution?
DNA mutations impact genetic diversity and evolution by introducing new genetic variations into a population. These mutations can lead to changes in traits and characteristics, which can be beneficial, harmful, or neutral. Over time, these variations can be selected for or against through natural selection, influencing the overall genetic makeup of a population and driving evolution.
Darwins theory of evolution differences between species may result of?
Darwin's theory of evolution suggests that differences between species can result from random mutations and natural selection. Random mutations introduce genetic variations within a population, and natural selection acts on these variations to favor those traits that confer a reproductive advantage, leading to changes in the population over time. This process ultimately drives the divergence of species from a common ancestor.
What is the relationship between evolution and genetics?
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
What is a substitution in biology and how does it impact genetic variation and evolution?
In biology, a substitution is a type of genetic mutation where one nucleotide in a DNA sequence is replaced by another. This can impact genetic variation and evolution by introducing new genetic variations into a population. Over time, these substitutions can accumulate and lead to the formation of new traits, potentially driving evolution.
Darwins theory of evolution did not contain the concept that?
Genetic variations are produced by mutations and sexual recombination
Does evolution happen on a genetic level?
Yes, evolution occurs on a genetic level through changes in the frequency of genetic variations over successive generations. These genetic variations can lead to changes in an organism's traits that can be passed on to offspring, driving evolution.
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.
Is inheritance an important part if the process of evolution?
Yes, inheritance is a fundamental component of evolution. The passing on of genetic information from one generation to the next allows for variations to accumulate and be passed down, forming the basis of genetic diversity and driving evolution through natural selection.
What does substitution mean in the field of biology and how does it impact genetic variation and evolution?
In biology, substitution refers to a type of genetic mutation where one nucleotide in a DNA sequence is replaced by another. This can impact genetic variation and evolution by introducing new genetic variations into a population. Over time, these substitutions can accumulate and lead to the formation of new traits, potentially driving evolution.
What is the result of variations in copying of DNA?
Variations in copying of DNA can lead to mutations, which are changes in the DNA sequence. These mutations can result in genetic diversity, evolution, and potentially lead to genetic disorders or diseases.
