Answer:
allows the recombination of genetic information
Explanation:
Crossing over is a process that occurs only in meiotic division in sexually reproducing organisms. It is the process whereby the segments of a gene are exchanged between the non-sister chromatids of homologous chromosomes.
Due to this crossing over process that occurs in prophase I of meiosis, the alleles of a chromosomes are recombined to ensure genetic diversity. Hence, according to this question, crossing over results in additional genetic variation during meiosis because it allows the recombination of genetic information.
<span>The main light-absorbing pigment for photosynthesis is known as chlorophyll. This light absorbing pigment is found in many organisms, primarily in a variety of plant and bacteria species. Chlorophyll is necessary because it allows the light to be absorbed and allow energy to be absorbed by the organism in order to carry out a multitude of metabolic processes.</span>
