This is a brassica oleracea flower, its petals are yellow.

Inside of it is where all the reproduction happens.

This is the male part of the flower, known as the stamen. It has 

a filament coming up from the base of the flower. At the 

tip of each filament is an anther, where

 meiosis takes place, producing pollen grains. It produces

 male haploid gametophytes.

This is the female part of the flower known as carpel, it is the 

innermost floral part. It consists a stalk called a style. It has a sticky tip called stigma, in the sticky tip is where the pollen grain gets stuck.

Further in the dissection, we are exposed nothing left but the ovary.

The ovary is the green tube and in it there are small green ovules.

 This is a picture of the whole Brassica olereacea flower from one of the plants in the garden.  This type of flower goes through meiosis for reproduction. Not every plant goes through meiosis but this particular flower does. Meiosis is the process f which the number of chromosomes per cell is cut in half through the separation of homologs chromosomes in a diploid cell.

 This image shows the anthers. An anther is the flower structure where the haploid male gametophytes are being produced. Anthers are at the tip of each filament. A filament is a long thin stalk that helps support the anther. An anther is an oval sac where meiosis takes place.

 In this image the carpel was cut in half. The little circles inside are called ovules. An ovule is a structure in the seed cones where the female gametophytes are developed. These are unfertilized eggs waiting for meiosis to begin so that the flower reproduces.

Here is the carpel of the flower.  The carpel is the innermost part of the entire flower that produces the female gametophytes. Carpels are also known as pistils. Each carpel forms an ovary which contains one or even more ovules where the female gametophytes are made.

Who Wants to Live a Million Years: Analysis of a Natural Selection Simulation

1. For me to win in the game, it took me about 14 times. It was difficult to get the species all the necessary phenotype combinations. After getting a great combination, I won the game.
2.At first I would only make combinations of all furry species or all tall species, this clearly did not seem to work out. After, I made a combination of long legs, fur coat, and other necessary traits for the species to survive and it finally lived for a million years. All of the traits and phenotypes made the species able to survive and not die too soon.
3.The species would be affected by genetic drift because when a type of genetic drift occurs, the species start to die. Just like in the game when it was cold and the species did not have a fur coat they started to die.
4. Most of the tall species were more dominant than the short ones with a lot of fur. The ones that were short, fat, and furry died when they got overheated.
5. In hot conditions, the species that are less fat and have no fur will survive. During the cold, the stout and furry species survived better. When there was a predator, the species with long legs survived since they could run away. When the plants started to grow tall, the species with long legs seemed to survived because they could reach the plants.
6.I would improve this simulation to represent natural selection and biological evolution by having more specific traits and combinations to adapt to the environment. Also,  I would make the evolution of the species more clear and specific. Lastly, I'd get the species better traits to adapt to the global warming environment.

2. I believe there is so much variability in the domestic forms of Brassica Oleracea because they are all from a historical group of Crucifera , a four petalled flower. Some are curly-leafed, smooth-leafed, and some are wild type, but they are all the same genus or species. Artificial selection requires a farmer to to determine which individuals possess the key characteristics to pass on to the next generation.  The cultivars of B. oleracea are grouped by developmental form into seven major cultivar groups.

The Brassica oleracea all have the same texture of its stem and leafs. I think this because they are practically from the same ancestors hence the same name brand of the packages that they come from.

GATTACA Essay

In the movie GATTACA directed by Andrew Niccol made in 2007 is about an “in-valid” young man,Vincent, who tries to change many major things about him to become “valid” to live his long dream of going into space.

    There is one quote in the beginning of the movie that I believed had a lot of meaning behind it. “This child is still you, simply the best of you. You could conceive naturally a thousand times and never get the same results” said the Genetic counselor (GATTACA Niccol). This quote means that one can continue to keep trying for another child but each child will come out differently. One’s child will not come out perfectly without health problems or genetic features. No matter what the child still has the parents genetic identity and that can not be changed.

    Through out the film there were numerous recurring symbols such as glass/water also being an obstacle that Vincent must face. For example, Vincent wears glasses due to the fact that he’s near cited. His glasses is one way to know that he is “in-valid” because one who is “valid” is far cited. Moving on, he must wear contacts to look just like Jerome’s eyes.

    Vincent needs almost everything from Jerome, such as: urine samples, blood, fingerprints, and contacts to be “valid”. Both Jerome and Vincent get a significant amount of benefits out of their relationship. Vincent gets what he needs to be able to go to space and Jerome gets the reputation of it. Since Jerome can not walk or have the heart to not give up, he will be one to be known for going into space.

    I would like to take the opportunity to select special traits for my child, but I would be happy either way my child would turn out. Even if my child had traits I did not chose I would accept my child no matter what.

    Concluding, this movie has made me change my perspective on people how some people do not feel accepted and try to change themselves. If I lived in a world like Jerome and Vincent it would be very difficult to live a certain life like they do.

Who Wants to Live a Million Years:Analysis of a Natural Selection Stimulation

       It took me twelve generations to finally win one game. It took this long because I had to chose one of each species selection that has different features. I think this means that species have to have the best genetics and features to survive certain obstacles to survive up to a million years.

        I selected the tall red headed species, short species with stripes, and the short fat species with lots of fur.  I believe this helped me win because they reproduced with one another and made one whole new species that can survive.

        Yes, I believe the species would be greatly affected by genetic drift. When some type of genetic drift happens, most of the population of the species dies off. For example, when it is freezing cold and there is a species that has not fat and fur, it will most likely die off.

          The tall species seemed to be more dominant and the short species with no fur seemed recessive. I could tell because most of the species after reproducing turned out tall. This proves that the tall species is recessive.

           During cold conditions short, fat, and furry species best survives. Species with no fur will survive hot conditions. When there is a new predator on scene species with long legs and tall height will survive the invasion. Species with tall legs and long necks will be able to survive due to tal new plant resources.

            To improve natural selection and biological evolution the should be no pollution and poaching and stop global warming.
