Prophase 1 (APEX)
DNA and RNA are molecules responsible for heredity and variation in organisms. They carry genetic information that is passed down from one generation to the next, and mutations in these molecules can lead to variations within a species.
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
Yes, the process of independent assortment contributes to an increase in genetic variation by creating different combinations of alleles during meiosis, leading to a greater diversity of genetic traits in offspring.
During the process of mitosis, genetic variation is not directly contributed through crossing over. Crossing over occurs during meiosis, not mitosis. In crossing over, homologous chromosomes exchange genetic material, leading to genetic variation in offspring. Mitosis, on the other hand, is a cell division process that produces genetically identical daughter cells.
Crossing over during meiosis is a process where genetic material is exchanged between homologous chromosomes. This leads to genetic variation in offspring by creating new combinations of genes.
Meiosis is responsible for genetic variation
Genetic variation is one of the conditions required for Natural Selection to occur.
The first description of the process of genetic variation could probably be attributed to Charles Robert Darwin, who is the originator of the Theory of Evolution.
Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.

Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
Yes, the process of independent assortment contributes to an increase in genetic variation by creating different combinations of alleles during meiosis, leading to a greater diversity of genetic traits in offspring.

During the process of mitosis, genetic variation is not directly contributed through crossing over. Crossing over occurs during meiosis, not mitosis. In crossing over, homologous chromosomes exchange genetic material, leading to genetic variation in offspring. Mitosis, on the other hand, is a cell division process that produces genetically identical daughter cells.
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
Meiosis creates genetic variation through the production of 4 haploid daughter cells, each with random genetic combinations. Meiosis also creates genetic variation through the process called crossing over, where chromosome segments are exchanged.
