My favorite topic this year is genetics  because I find it really interesting how you can use the punnet squares to figure out the possibility of an offspring, and how the traits are recessive or dominant. As for my least favorite it would be the Kreb Cycle, because I could never understand how the cycle goes, so its difficult for me to remeber. If there was one thing I could it would be making cancer cells harmless, because since cancer is dangerous and had made people die from it I want to make them harmless. To do that I would have to invent some kind of medicine that people could drink, if they have cancer, so they can get rid of this disease.

DNA helped make investigating crimes more faster, because DNA is the evidence on who did the crime. DNA evidence has helped identify who the suspect is in sexual violence or rape. The police use either fingerprints or blood from the person who was killed to get the DNA of the suspect, because when the criminal kills somebody that is close to them they usually use a knife and stab them, and when they did they either cut themselves. So it would be easy for investigators to find out who was the suspect by using the blood and match DNA in the criminal's database. Each person carried a genetic fingerprint in his or her DNA, so every person could be identified solely by the sequence of their base pairs. Instead, scientists are able to use a shorter method due to repeating patterns in the DNA. These patterns do not, however, give an individual "fingerprint," but they are able to determine whether two DNA samples are from the same person, related people, or non-related people. This is called DNA fingerprinting or profiling. So with DNA evidence it makes it alot more easier to find the suspect and without it, police would take long to figure out whos the suspect and perhaps might not even find the suspect and fail in criminal justice, since evidence is important for crimes.

In Gregor Mendel and his pea plant the P1 stands for parent generation, F1 stands for first filial (daughter) generation, and F2 stands for second filial (daughter) generation. So, for the Parent Cross, or the very first cross-breed Mendel did, which was between tall and short plants, the offspring were all Tt, each having a dominant allele and a recessive. Each F1 plant produces two types of gametes those with allele for tallness and shortness. So basically F1 inhearited P1's tallness, which is dominant, so all F1 plants are tall.
