Binocular cues--particularly retinal disparity and binocular convergence

Binocular cues are information (depth/distance) taken in by both eyes. The two main types of binocular cues are retinal disparity and binocular convergence.

Retinal disparity arises from the fact that our left and our right eyes, being a few centimeters apart, view images at slightly different angles. The two different images are merged into one and this allows us to perceive depth in the things we see around us.

Binocular convergence is the simultaneous inward movement of both eyes in order to maintain a single binocular vision. The closer the object is, the more inward rotation is required for the eyes. The degree of rotation of the eyes helps the brain to interpret the distance of the perceived objects.

Answer:

Natural selection causes change in allele frequencies within a population.

So option A is correct one.

Explanation:

Natural selection generally work on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and reproduce better than their peers, natural selection can increase the frequency of the helpful alleles from one generation to the next – that is, it can cause microevolution.
