Question

How does nature “select” phenotypes, such as bird beaks? Check all correct explanations. 1. Organisms can choose the genes that will make them most successful. 2. The environment influences which alleles an organism can pass on to its offspring. 3. Traits that suit the environment enable an organism to reproduce in greater numbers. 4. Traits that do not suit an environment make it harder for an organism to stay alive and reproduce.

Answer 1

The correct answers would be options 3 and 4.

Natural selection refers to a natural phenomenon by which organisms with survival traits tend to survive and reproduce more as compared to the organisms which lack such traits.

Due to this differential reproduction, survival traits tend to pass on to the offsprings and over several generations the phenotypic frequency of the population changes.
