What else can I help you with?
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. :)
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 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.
What does natural selection select for?
Natural selection selects for traits that increase an organism's ability to survive and reproduce in its environment. These traits are passed on to future generations, leading to an increase in their frequency in the population over time. Ultimately, natural selection acts to improve the fitness of individuals within a population.
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.
Explanation of Natural and Artificial Selection?
Artificial selection is when humans select traits, such as color or taste and breed for those traits. Natural selection chooses the creatures that are best able to give birth to more offspring, carrying on their genes. The environment chooses.
What in humans select traits that will be passed from one generation to another elective breeding or natural selection?
elective breeding
