Answer» The natural characteristics are transferred through genetics. In humans, each cell contains paired chromosomes which are composed of a polymer called deoxyribonucleic acid (DNA). Some of these cells divide to produce gametes (ova in females, sperm in males).

Each gamete now has one of each chromosome (instead of a pair) and each of those chromosomes is a semi-random mix of segments of the paired chromosomes from the parent. |
