Do Transposable Elements Reduce Genome Size?

Transposable Elements and Local Gene Duplication
This confirms that the change in TE content is the major reason for genome size reduction in the inverted regions. Besides the change in numbers, the TE composition was also altered in the inverted regions.

How do transposable elements affect genomes?

A transposable element (TE, transposon, or jumping gene) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. Transposition often results in duplication of the same genetic material.

Is genome size related to transposable elements?

The relationship between genome size and the percentage of transposons in 161 animal species evidenced that variations in genome size are linked to the amplification or the contraction of transposable elements.
