Without genetic variation, natural selection would not be possible. Explain why.

Answers

Answer 1

hello

Answer:

Explanation:

Without genetic variation, natural selection is only able to grow the number of allelomorphs that previously existed in the population. Natural selection can't select anything if there is no difference between individuals. Natural selection occurs through an interaction between the environment and the variability of the individual organisms making up a population. If every giraffe had the same neck length, there would be nothing to change and they would never have a long neck by now.

Answer 2

Genetic variation is the alteration of the genetic composition of an organism. Without genetic variation, natural selection is impossible as it selects species with divergent and favorable genes.

What are genetic variation and natural selection?

Genetic variation is the difference in the genetic composition or the genes of the organism of the population due to mutation and environmental conditions.

Natural selection is a process that selects the genetically different and fit organism that can survive and reproduce in altered conditions.

Therefore, natural selection occurs in a population with genetic variability.

Please help making brainliest if correct Explain how to solve the equation and then check the solution. 9 = q 4Sample Response: Use the inverse operation to isolate the variable. Undo the subtraction of 4 by adding 4 to both sides of the equation. 4 + 4 = 0, and 9 + 4 is 13. The solution is q = 13. Check the solution by substituting 13 for q in the original equation, and then simplify. 13 4 is 9 and 9 = 9 is a true statement, so 13 is the solution.
