Kodi J., Reading letter #8
Title: Genetic Fingerprinting
Author: Sally Morgan
Pg 1-84 of 84
This book talked about how every person, except identical twins, has a unique fingerprint. The beginnings of inheritance was first discovered in 1866 by Gregor Mendel when he was working with pea plants. Today, forensic scientist can use genetic fingerprinting to assist in police investigation. DNA can come from tissue, blood, or even the root of one hair. By studying genes, scientists can understand someone’s risk of getting a genetic disorder, such as cystic fibrosis.
In a crime scene investigation, I wonder if a forensic scientist could identify someone that was burnt. This story is important because it will help to make sure murderers and rapists in jail are actually guilty of their crimes. I found it interesting that environmental pollutants can alter a person’s DNA and can be passed on to children. Before I was born, the doctors had to test chromosomes in my amniotic fluid to see if I was going to have Down’s Syndrome…..but I didn’t. I thought this book was informative, but rather boring. The only good things were it had nice pictures, it was short and had biographies and a glossary in the back. I’d give it 2 stars. If you like the study of genetics, go ahead and read it.

Kodi,
Very logical explanation of the story. I enjoyed hearing about the story and i thought it was written well. It was a very appropriate length and hap a great reflection. Something you could work on though are some grammatical errors I noticed here and there.
