One of a Kind: The Wonders of Biodiversity


      -Leah Poapst

     Our group was experimenting with a cauliflower, which has died. The cauliflower is a vegetable that reproduces by seed. Our cauliflower was white (most common color), although cauliflower can vary in different colors such as orange, green, purple and white. My teams cauliflower came from a package of multiple seeds, therefore we can only predict what it would look like from the photo. Our plant would have inherited a large, fluffy, and white center like its parent plant. The cauliflower would acquire some of these traits (if it had survived) by meiosis, in which the result of the two divisions of a diploid cell would be four haploid cells. This means that the next generation of the plant would have half the genetic material of the original cell. We cannot predict the traits of the offspring but we can imagine a similar look, due its dominant traits.
The varieties of Brassica oleracea was probably changed during the process of meiosis, due to crossing-over. Although my classmates plants look different they may still have some similarites.
