Genetics |
Gene-a unit of heredity which is transferred from a parent to offspring and determines some characteristic of the offspring. Allele-a variant form of a given gene. Chromosome-a structure in the cell carrying genetic information in the form of genes. Phenotype-the set of observable characteristics of an individual. Genotype-is the part of the genetic makeup of a cell, and therefore of any individual, which determines one of its characteristics Central dogma-the process of transforming DNA into proteins Homologous-Having similar structure and anatomical position Heterogeneous-having two different or non similar traits Mutations-a copying error in the DNA process resulting in a physical change Punnent Square-diagram used in predicting phenotype |
Dominant-are those that are expressed or seen when a heterozygous genotype is present.
Recessive-can be carried in a person's genes without appearing in that person. Co-dominant-Relating to two alleles of a gene pair in a heterozygote that are both fully expressed.(EX. when combining red and white you get pink) Incomplete Dominance-is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. Inheritance-is a basic principle of genetics and explains how characteristics are passed from one generation to the next. Variation-any difference between cells caused by genetic differences Haploid-has a single set of chromosomes Diploid-two complete sets of chromosomes |
Fingerprinting |
Pedigree |
There are 3 main types of finger prints: Whirl, loop, and arch. However what makes each person's fingerprint different is the prominence of the trait or the minute changes in the fingerprint. Along with this fingerprints are a perfect example of co- dominance. Since Whirl and arch are the two dominant traits when you get a combo of the two you end up with a loop. Because of the vast difference in fingerprints they can be used to identify a specific person.

These charts show the pedigree, or family history of an individual or group of people. In our investigation, we used the individual stories of the suspects to patch together a network of relationships between them, and also any hereditary diseases that may have affected them. This can be used to discover any motives or possible connections between the victim(s) and suspects.
