Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
What requires natural selection to occur in a population?
genetic variation
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Why does variation occurs?
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
What two factors introduce genetic variation during the process of meiosis?
The two factors that introduce genetic variation during the process of meiosis are independent assortment and chromosomal crossover. These occur during prophase 1 and anaphase 1 of meiosis.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
What requires natural selection to occur in a population?
genetic variation
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
What characteristic within populations causes natural to occur?
genetic variation
The degree of adaptation that can occur in a population is limited by?
the amount and kind of genetic variation in a population
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
Does variation occur in plants?
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.
Why does variation occurs?
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
