Genetic Variety Blog

Genetic variety has to do with a lot about our rebops. During the process of creating a new child, our previous children came in contact with other bugs that had different traits. This made our resulting bug different form their original parent appearance. For example my first bug did not have wings, but my mates bug had a dominant case of wings so my child ended up having wings. This shows that the genes can interchange with each other during fertilization and create the child's original genotypes to change. Also this is a reason why no two children look the same, because there is a whole new set of genes to link with once you fertilize with your mate. Also, my first child had a yellow body and once I fertilized with my mates first child, my new child had a green body. This just shows that once original genes are meet with new genes the resulting child might have mixed genetic information from both parents.

These fish might have come from the same family and their parents' genes fertilized to get children will all different skin colors.

Science 3/5/10

The concept of dihybrid crossing is to have a set of four genes going across and vertically. This gives you more options to see your outcome in the things that you produce. If i were to go back into the future, i would tell myself that when figuring out the percent chance to write down the recesive and dominant traits so that I would be more organized when figuring out the problem. Below is a dihybrid cross:

The next concept is selective breeding. This term means that you take two things and morph them together on purpose. This would be like having a mix between a dog and a cat or a deer and a moose.

Selective breeding is on purpose while as regular breeding in not planned. During our discussion o selective breeding I didn't have any trouble with it so, i would not recommend myself to ch

ange yet.

The last term is incomplete and co-dominance. Incomplete dominance is when two dominant allele mix together. Co-dominance means to have both dominant alleles separate, but together in a separate way. I would just tell myself for the future to make sure i have my definitions straight so i don't make a careless mistake on a quiz or test. This following pictures are incomplete dominance and co-dominance:

The end :)

meiosis and mitosis

This week we started to learn about meiosis. Its a 11 step process and makes four (tetra) animal cells. The phases/ steps are:

1. diploid cell (2N)
2. prophase I
3. metaphase I
4. anaphase I
5. telophase I
6. prophase II
7. metaphase II
8. anaphase II
9. telophase II
10. gamete (1N)
11. material paternal

Also in meiosis four cells are being made instead of just one, like in mitosis. Also both mitosis and meiosis have overall the same phases, except for meiosis has it has double the phases like prophase I and prophase II. Meiosis also creates animal cells as appose to mitosis which makes any type of cell. Lastly, Meiosis has two adde phases called diploid cell (2N) which occurs at the begining of the cycle and gamete which takes place at the end of meiosis.

cell reproduction

This week we learned about asexual reproduction. The following steps are in order in which they occur in the cell reproduction cycle.

• The cell has to be in a safe enviornment, and if not the cell will continue to rest.
• If the enviornment has been noticed as safe to the cell than the cell will continue to grow and produce.
• The cell starts to copy and unwrap DNA until there is two.
• After the copy the cell continues to grow.
• Along with th safe enviornmet copied DNA, and the cell is big enough the cell will continue to grow.
• DNA enters cell and the cromatid pair separate to create an equal new cell nucleous.

mighty mitosis

We learned about mitosis this week. During mitosis the nucleous cell divides. There are four steps in mitosis called prophase, metaphase, anaphase, and telophase. During each of these steps, they all lead up to a new nucleous at each end of the cell. Also there is another step called interphase, and during this step the chromosomes spread out in the nuclous. During prophase, chromatin coils up and folds the strands of genetic material. The cromatid pair forms an x- shape and each half of the x shape has the same genetic information. During metaphase, the chromatid x's line up in the cell. During anaphase the two halves of the x- separarate from eachother and the cromosomes move apart to each opposite end of the cell. Lastly, during telophase a new nuclear membrane forms around each set of chromosomes. This results of a new nucleous at each end of the cell.

This week we were making analogies to cells after we finished watching a video clip. The video stated that people live on streets and streets are in villiages/cities, cities are in countries, countries are in continents, continents are in the earth, earth is in our solar system, our solar system is in our galaxy and our galaxy is in our universe. This all is telling something. These are all layers into creating our universe. This related to our cells and how they are just made up of layers. By knowing this information we can now make analogies and compare everyday things like a school and a hotel building to a cell. Wedo this by taking a specific part like the foundation of a building and calling it the cell wall or membrane since they both surve the same purpose.

awesome alex!

This week was all about Photosynthesis and Fermination. First photosynthesis is just like a huge cirlce along with respiration. From the chloroplast to the mitocondeia produces energy (sunlight and carbohydratrates), water (H2O), oxygen

(O2), and carbon dioxide (CO2). From the mitocondria to the chloplast produces energy, H2O, O2, and CO2. From this you can see the cycle that is being shown. Along with respirationa dn photosynthesis, if animals and plants are both part of the respiration cycle if all animals dyed than something would get messed up. Animals inhale oxygen from the plants and then exhale carbon dioxide. Then the plants give off oxygen so WE can breath and vise versa(only with carbin dioxide). Since this is a cycle niether species would be able to get back that oxygen or carbon dioxide to keep the cycle continuous. Fermination is respiration without oxygen. The reactants of fermination are glucose which are sugar, and the products are carbin dioxide, alcohol, energy and for animals lactic acid. We also did a fermination experiment.

First to see if when we put reactants to fermination, yeast and sugar, and water, into the test tube we would get the smell of alcohol and carbin dioxide would be "ehaled". To tell if there was carbin dioxide being exhaled we put a balloon over the top of the test tube to see. Our results were positive to our first prediction!

Lastly we learned about DNA. DNA is just your parents dna mixed together since no to people have the same DNA except for twins. As we learned DNA is not a cell beacuse it is made up of cells. I think that DNA is formed into a long stringy form because DNA is made up of a bunch of cells, and once they all come together they form this type of formation. :)
