<span>In biological terms, the structure of a species is usually best adapted to give it the most advantageous functional ability, though this is not always the case. When a structure has a function that allows the species to survive and promulgate its genetic structure, the individual will be more likely to reproduce its genotype over those that are not structurally advantageous.</span>
Because of the Law of Segregation, the ratio would be 1:3. Meaning 3 kids with lactase persistence.
The answer to this question would be: better-stabilized knee joint
The quadriceps femoris muscle is located in the anterior part of the femur. This group of muscle is used for extension. It has no role in flexion, abduction or adduction. In general, training a muscle will stabilize the nearby joint. In this case, the quadriceps will stabilize the knee joint.
Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.
Best answer is A.
