Why would natural selection not occur in this poplutation?
What population? Perhaps you mean if there were no variation for natural selection to select from.
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
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 is variation important for natural selection and what are the main sources of this variation?
Without variation natural selection would have nothing to select from that would confer survivability and reproductive success. on the organisms being selected against the organisms conspecifics and the immediate environment. Mutation and sexual recombination provide the main sources of this variation that is needed to make selection work. Mutation is the variation presented that causes the real adaptive change that can lead to speciation.
6 Explain why evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
If there is not reproductive fitness conveyed by a variant trait, then natural selection has nothing to select and nothing to promote into the populational gene pool.
How does environment select organisms?
natural selection

What is the process where animal select mates with traits best suited for survival?
natural selection. :)
What does natural selection select for?
Natural selection select depending on 2 things. 1. The ability to survive in a habitat until reprocing 2. The ability to reproduce and to get a mate
Is considered an important factor in natural selection?
Mutation is the important " starter " of the adaptive change engendered by natural selection. Variation is key to selection and without variation in organisms there would be nothing to select from for the survival and reproductive success of the organism against the immediate environment.
Is inheritance a requirement for natural selection?
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
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 there be variation in a population in order for natural selection to occur?
What would there be to select from if all the organisms in a population were not different in morphology and behavior. Some of these differences are reproductively successful against the immediate environment, and that environment is the natural selector.
Why does evolution evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
Differential selection is just that, differential. Some variation is marginally superior to another variation us fitness difference, so the key is to have variation. Then natural selection will " see " this slight variation and select the better adapted trait against the background of the immediate environment.
A technique in which breeders select particular traits to be passed on is called what?
A technique in which breeders select particular traits to be passed on is called? A)Natural Selection B)Artificial Selection C)Darwin Selection D)Synthetic geneology
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
Why is it hard for natural selection to stop the declin of the cheetah population?
No genetic variation in the cheetah population gene pool, so natural selection has nothing to select from and the inbreeding depression keeps deleterious traits breeding true among cheetahs and natural selection can not eliminate them from the gene pool.
