Question

which of the following describes a likely result of genetic variation in a population of lizards? choose 2 answers: a some lizards will have traits that help them survive longer than others under specific environmental conditions. b the population will have phenotypic variation, such as differences in scale color or limb length. c all lizards in the population will produce the same number of offspring because, being the same species, they have the same genetic variations.

Explanation:

• Option A: Genetic variation leads to different traits. Some traits will be advantageous in specific environments, allowing those lizards to survive longer. This is consistent with natural selection concepts.
• Option B: Genetic variation is the basis for phenotypic variation (observable traits). So differences in scale color, limb length, etc., are expected due to genetic differences.
• Option C: Genetic variation means individuals are not identical. Traits related to reproduction (like number of offspring) can vary, so this statement is incorrect as it claims all have the same genetic variations and same offspring number.

Answer:

A. Some lizards will have traits that help them survive longer than others under specific environmental conditions.
B. The population will have phenotypic variation, such as differences in scale color or limb length.
