Yes, chromosomes can change after birth.
Changes to chromosomes can lead to issues with growth, development, and how the body functions. According to research, these changes can occur not only during the formation of reproductive cells or early fetal development but also in any cell after birth (Reference: 12-May-2021).
How Chromosome Changes Happen
Chromosome changes can happen in different ways and at different times:
- During reproductive cell formation: Errors can occur when eggs and sperm are being made.
- Early fetal development: Changes can happen as the fetus is developing.
- After birth: Chromosomes in any cell can change throughout a person's life (Reference: 12-May-2021).
Impact of Chromosome Changes
A change in chromosome number or structure can have significant effects on health.
| Timing | Impact |
|---|---|
| During cell reproduction | Errors in cell division can result in missing or extra chromosomes in the new cell. |
| After birth | Changes can impact a single cell or multiple cells. |
Examples of Chromosome Changes
While some chromosome changes are inherited, others can arise spontaneously.
- Mutations: Sometimes, exposure to certain chemicals or radiation can cause changes in chromosomes.
- Errors during cell division: Mistakes during mitosis (cell division in somatic cells) or meiosis (cell division in sex cells) can lead to cells with abnormal chromosome numbers.
