Scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.
<h3>Why use the Brassica plants in genetic studies?</h3>
Brassica plants are considered model organisms in genetic studies because they have a short period of growth (around 30 days), which allows the analysis of a high number of generations in less time.
Moreover, the genome of Brassica plants contains 24 Gigabases (24 billion nucleotide bases), which is a high number to be considered a model organism in genetic studies.
In conclusion, scientists often experiment with Brassica plants because they have a relatively short growth period, and they may represent model organisms for genetic studies.
