It happnes when genes are being passed down from the parent to the offspring and environmental differences alter the genes being passed down
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.
no there is no genetic variation for natural selection to act upon
Genetic drift has a larger effect on smaller populations.
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.
Variation occurs because of mutations in the genetic code.Mutaions occur when one of the nitrogen bases are in the wrong spot like if aa is next to each other in the wrong sequence then the mutations occur
Genetic variation is one of the conditions required for Natural Selection to occur.
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.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Genetic variation is necessary for evolution to occur, as it provides the raw material for natural selection to act upon. This variation can arise from mutations, genetic recombination, or gene flow.
Without variation there is nothing to select from.
genetic variation
the amount and kind of genetic variation in a population
no there is no genetic variation for natural selection to act upon
Loss of genetic variation(:Novanet:)
Much more morphological variation occurs in plants. Genetic variation is the big variation in plants because of polyploidy; this doubling, tripling and halving of chromosome number in the mating of two plants not only leads to great variation in genetic material, but also leads to great speciation in plants.
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.
Genetic drift has a larger effect on smaller populations.
