Match the following to their correct definitions

Draggable item		Corresponding Item
Chromosome reduction		The process during meiosis results in the random distribution of chromosomes to gametes.
Independent assortment		The process that lead to genetic diversity and it ensures the survival of a species.
Crossing over		The process which the chromosome number is reduced to ensure that each child receives a complete set of chromosomes.

Determine the most accurate explanation of meiosis and clarify how this process guarantees that the resulting gametes contain haploid(half) number of chromosome.

Meiosis randomly chooses which chromosomes to retain, resulting in each genetically distinct gamete possessing a unique number of chromosomes.

Meiosis involves a single division process, producing two daughter cells that are genetically identical to the parent cell and maintain the same chromosome count.

Meiosis consists of two cycles of cell division, leading to four genetically unique daughter cells, each containing half the chromosome count.

Meiosis involves the duplication of chromosomes without dividing them, resulting in the formation of four genetically identical gametes, each containing the complete set of chromosomes.
