Answer:
Crossing over increases the genetic variation
Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction
Explanation:
Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

❖ The term that matches this statement is Metaphase. Metaphase occurs in Mitosis and Meiosis. The homologous chromosomes line up in single file.

Answer:
This phenomenon is known by neuroscientists as Neuroplasticity, or brain plasticity
Explanation:
Think of plasticity, Neuroplasticity, or brain plasticity, is the simplest terms, as the ability of parts of the brain to adapt their function or ability to change throughout life.
Structural plasticity - brains ability to change in response to the environment.
Functional plasticity-brains ability to change in response to the activities.
The pattern of inheritance is called codominance when the father has type A and the mother has type B and the kids have type AB blood. This is when the both of the alleles will show equal dominance/impact after mating. The type A blood has the gene pattern iAi or iAiA. The type B blood has the gene pattern iBi or iBiB. The correct answer to this question is "codominance."
