Natural and Artificial Selection
Mutation and recombination are the two main sources of genetic variation in a population. Mutations are changes in the DNA sequence, while recombination occurs through the mixing of genetic material during the formation of gametes.
Genetic variation. Mutations introduce new genetic changes that can be passed on to offspring, while genetic shuffling during sexual reproduction mixes genetic material from two parents to create unique combinations of genes in the offspring.
Some sources of variation include genetic differences, environmental factors, random mutations, and genetic recombination during sexual reproduction. These variations contribute to the diversity of traits and characteristics within a population.
In mitosis, one cell divides into two identical cells, resulting in no genetic variation. There is only one cell division in mitosis. In meiosis, one cell divides into four cells, each with different genetic material, leading to genetic variation. Meiosis involves two cell divisions.
In sexual reproduction, offspring inherit genetic material from two parents, leading to greater genetic diversity and variation among offspring. In asexual reproduction, offspring are genetically identical to the parent, resulting in less genetic diversity and variation.
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
Mutation and recombination are the two main sources of genetic variation in a population. Mutations are changes in the DNA sequence, while recombination occurs through the mixing of genetic material during the formation of gametes.
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.
The main source of genetic variation is a large population with a large gene pool.
Genetic variation. Mutations introduce new genetic changes that can be passed on to offspring, while genetic shuffling during sexual reproduction mixes genetic material from two parents to create unique combinations of genes in the offspring.
The two main sources of genetic variation are mutations, which are changes in the DNA sequence, and recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. These processes contribute to genetic diversity within populations.

Other sources of genetic variation in a population include genetic mutations, genetic recombination during sexual reproduction, and gene flow from migration of individuals between populations. These processes can introduce new genetic combinations and alleles into the population, leading to increased genetic diversity.
