In Meiosis 1, there is a duplication of chromosomes followed by the division of the cell into 2 diploid (regular number of chromosome pairs) cells. In humans this first division would result in 2 cell bodies each containing 23 pairs of chromosomes or 46 chromosomes.

In Meiosis 2, there is another division, but this time without the duplication of chromosomes. So the resulting cell bodies would be haploid with only 23 chromosomes (not pairs) each. Examples would be sperm and ovum.

meiosis 1 is the cell division im which number of chromosomes decreases to half. And meiosis 2 is just like mitosi

Meiosis the process where sex cells are formed. The amount of chromosomes in a sex cell is half the number of the amount of chromosomes in a body cell.
In meiosis 1, the chromosomes in a cell duplicate. Each set of chromosomes is distributed into two new cells. In meiosis 2, each chromosome is split again, so that one strand of each chromosome is in a new cell. At the end of meiosis, 4 sex cells are produced, each with half the number of chromosomes as the body cells.
Chromosomes are made up of genes. Each strand in a chromosome is made up of the same order of genes.
once two sex cells "combine," a complete set of chromosomes are formed, so that half of the genes come from one parent, and half come from another.
