Student Blog Post #7 - Sayra

     We are experimenting with Brassica Oleracea. It has waxy,round leaves and is grown in north temperate regions. The plants need a cool growing season and lots of moisture if you want them to grow. It originated from western and southern Europe. Some of the plants in these species are cauliflower, broccoli, kale, cabbage, and kohlrabi.
(The pictures are the same ones that Jenny and Jacob posted)
     Here are some pictures of how our our plant looks right now. You can see that they are starting to die since other plants are kind of taking over it.
     If we want to predict what traits our plants have, we have to know what traits they have. For example, if our plant has heterozygous yellow stem genes it would have Pp (example letters.) If its pollen mixes with a homozygous recessive green stem plant, it would have pp genes. When they make offspring, it will have different options for traits. A punnet square will help you predict the traits that the offspring will have.
     The plants will have an offspring that can be 50% heterozygous yellow stems, and another 50% chance of having homozygous recessive green stems. It is a mixture of both the parents genes which means that it is possible but very unlikely that it will look like one of its parent plants.
     This is a picture of kohlrabi. The way it looks has been changed over the years. It has changed by generations of itself growing. This is like how offspring don't always look like their parents. Kohlrabi does not look exactly like the way it did before.
