What happens in crossing over? Why is it important for sexually reproducing organisms, and what is one of the consequences of er
BaLLatris [955]

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.

Each genetic outcome of a genetic cross between the same parents is ______ all previous outcomes. multiple choice question.
tino4ka555 [31]

A genetic outcome of a genetic cross between the same parents is independent of previous outcomes.

<h3>What is genetic variation?</h3>

Genetic variation can be defined as the genetic poll of an organism, which is the raw material trough which evolution can occur by natural selection.

During sexual reproduction, the formation of gametes generates different genetic backgrounds which are independent of distinct gametes.

In conclusion, each genetic outcome of a genetic cross between the same parents is independent of all previous outcomes.
