How does DNA get passed from one generation to the next?

In the chromosomes of the egg and sperm.

chromosomes split apart from both "parents" then that set from the mother attaches to the set that the father gives off. (the chromosomes carry DNA)

DNA is the genetic material that carries the instructions for the development, functioning, and reproduction of all living organisms. The process by which DNA is passed from one generation to the next is called "inheritance" and occurs through a mechanism known as "sexual reproduction." Here's how it happens:

1. Gamete Formation: In multicellular organisms, specialized reproductive cells called gametes are produced. In humans, these are egg cells in females and sperm cells in males. During a process called meiosis, the original cells divide, reducing their genetic material by half.

2. Fertilization: When a sperm cell fuses with an egg cell during sexual intercourse or reproduction, fertilization occurs. This results in the formation of a zygote, which is the first cell of the new individual.

3. DNA Combining: Each gamete carries half of the genetic information required to form a complete organism. During fertilization, the sperm and egg cells each contribute their genetic material, containing chromosomes made up of DNA. The combination of these genetic materials creates a unique set of chromosomes that determine the traits of the offspring.

4. Cell Division: After fertilization, the zygote undergoes mitosis, a process of cell division. This division results in the growth and development of the newly formed organism, with the genetic information from the parents being replicated and distributed to each new cell.

5. Passing on DNA: As the organs and tissues develop, the DNA carried by the cells in the zygote is distributed throughout the body of the growing individual. This DNA contains the instructions for the development of each component, including physical characteristics and various aspects of the organism's physiology.

Overall, the process of sexual reproduction ensures that genetic information is passed down from one generation to the next, allowing for genetic variation and the perpetuation of species over time.
