DNA Selection
How DNA for a new baby is usually selected is interconnected with a process called meiosis.
Meiosis is a form of cell division in the process of sexual reproduction. It divides twice; in which a diploid cell divides into four haploid cells (referred to as gametes) each with half the number of chromosomes of the parent cell.
Another form of cell division associated with meiosis is mitosis.
Mitosis is the division of the nucleus of a cell. It is involved in the process of asexual reproduction. Mitosis is associated with growth and cell replacement which results in two daughter cells that have all the same genetic material (DNA), and the same number and type of chromosomes as the parent cell.

One set of parents can have an almost unlimited number of possibilities for the genetic makeup of each child by the DNA (genes), traits, and characteristics they can produce or inherit. Another reason is the crossing over that occurs in meiosis. Crossing over is what makes the child unique and different. They can inherit their own genes instead of just the parents.
This picture shows the parent and its matching partner from the paternal parent. It is possible for homologous chromosomes to contain different alleles (one of two or more alternative forms of a gene) for the same gene.
