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 :)
