Understanding Polyploidy in Plants: Implications and Techniques

Polyploidy is common in plants, with various crops like apple, banana, and watermelon displaying different levels of ploidy. This phenomenon influences characteristics and breeding strategies. Techniques like crushing bananas to separate cells, using hypotonic water to swell cells, adding salt to aid DNA molecule interactions, and utilizing cold alcohol to collect DNA are employed in studying polyploidy in plants.

Presentation Transcript

1. Many plants are polyploids Humans (2n) Triploid (3n) crops: apple, BANANA, watermelon Tetraploid crops (4n) apple, cotton, potato, peanut Hexaploid (6n) crops: kiwi Octaploid (8n) crops: strawberry, sugar cane, pansies

2. Crushing the bananas helps separate cells Hypotonic water helps cells swell bigger.

Adding SALT (Na+Cl-) helps DNA molecules with NEGATIVE charges stick together. Soap -helps break down cell membranes and release DNA

4. Cold alcohol helps the DNA precipitate (come out of solution) so it can be collected.
