Answer:
We obtain DNA from both our father and mother, as they contribute it through the gametes.
Step-by-step explanation:
Each human being has 46 chromosomes, each of which is made up of DNA molecules and contains the genes that determine its appearance and function.
Both parents produce sex cells, called gametes, which contain half of the genetic information —23 chromosomes— that will be shared to form a new individual. So, each person shares both his father's and mother's DNA, and their characteristics will be the result of the combination of both DNAs.
