A Punnett square is used to show the possible ways alleles can combine. It is a grid system that helps predict the outcome of genetic crosses between two individuals.
DNA fingerprinting (aka DNA profiling) is a scientific procedure used to determine identity or parentage using DNA. Variable Number Tandem Repeats (VNTR) are found in the nucleotides of a DNA strand. When there is a pattern of two or more nucleotides that is repeated, and the repeated patterns are directly adjacent to each other (CATCATCAT) this is a VNTR. These VNTR show up when used in gel electrophoresis, and this outcome can be used to compare DNA samples. If the pattern in the gel for a a blood sample matches the pattern in the gel for an adult, the blood most likely belongs to the adult.

each person has a unique DNA sequence, except for identical twins. By analyzing specific regions of an individual's DNA, scientists can create a unique genetic profile that can be used for identification purposes. This technique is widely used in forensics, paternity testing, and other applications.
Forensic identification: DNA fingerprinting is commonly used in criminal investigations to match suspects to crime scene evidence or to identify victims. Paternity testing: DNA fingerprinting can also be used to determine biological relationships, such as confirming paternity or maternity in cases of disputed parentage.
A new discovery or technology in medicine can greatly assist in our health. Genetic engineering and DNA fingerprinting are just two of the examples that biology can be positively used.

The two most often used methods in DNA fingerprinting are polymerase chain reaction (PCR) and gel electrophoresis. PCR is used to amplify the DNA samples, while gel electrophoresis is used to separate the DNA fragments based on their size.

DNA fingerprinting may not be appropriate when trying to identify identical twins, as they share the same genetic profile. It may also not be suitable for trace amounts of DNA or degraded samples that are not suitable for analysis. Additionally, DNA fingerprinting may not be the best tool for identifying individuals within a large population or group where many individuals share similar genetic profiles.

Genetic relatedness is a measure of the similarity of genetic material between two individuals or groups. It is used to determine the degree of genetic similarity and common ancestry between them.

The two main ways of reproduction are sexual reproduction, which involves the combination of genetic material from two parents to create offspring with genetic diversity, and asexual reproduction, which involves producing offspring without the need for genetic material from another individual.
