Detailed explanation-1: -There are now two cells, and each cell contains half the number of chromosomes as the parent cell. In addition, the two daughter cells are not genetically identical to each other because of the recombination that occurred during prophase I (Figure 4).

Detailed explanation-2: -Each daughter cell has half the number of chromosomes as compared to their parents (one copy of each chromosome). The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1.

Detailed explanation-3: -Explanation: Crossing over occurs when chromosomal homologs exchange information during metaphase of Meiosis I. During this stage, homologous chromosomes line up on the metaphase plate and exchange genetic information.

Detailed explanation-4: -Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes-one from the mother and one from the father-line up, parts of the chromosome can be switched. The two chromosomes contain the same genes, but may have different forms of the genes.

Detailed explanation-5: -Crossing-over increases genetic variation by creating different chromosomes in offspring in comparison with their parents. The amount of genetic variation in a population is important because natural selection is dependent upon varying alleles to increase or decrease their frequencies.
