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.

Individuals adapt to their environments and, thereby, evolve

Explanation:

Natural selection is the main process which advances evolution by aiding organisms to survive and produce more offspring through adapting more to their environment. Mutations, gene transfer, and genetic variations also drive evolution.

Both natural selection and evolution work on genetic behaviors in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations.  Examples of evolution is the disappearing of tail bone, decreased head size and for natural selection example is the long and short necked giraffe.

Vaselesa [24]

Answer:

The presence of an additional chromosome

Explanation:

Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.

Definition of Trisomy:

A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.
