Vertical gene transfer

Definition

Vertical gene transfer is the transmission of genetic material from parent to offspring during reproduction. It ensures the continuity of genetic information across generations.

5 Must Know Facts For Your Next Test

1. Vertical gene transfer occurs in both prokaryotes and eukaryotes.
2. In asexual reproduction, vertical gene transfer involves the replication of the entire genome.
3. Mutations occurring in the parent's DNA can be passed on to offspring via vertical gene transfer.
4. Vertical gene transfer contributes less to genetic diversity compared to horizontal gene transfer in prokaryotes.
5. It is crucial for maintaining species-specific traits and characteristics.
