I believe that the principles of inheritance were formulated based on observations on the outcomes of breeding experiments. The underlying processes were unknown at the time. Mendel's observations and conclusions are summarized in the following two principles or laws. The law of segregation which states that for any trait, each parent's pairing of genes (alleles) split and one gene passes passes from each parent to an offspring. The other is the law of independent assortment which states that different pairs of alleles are passed onto the offspring independently of each other.
<h2>Gel electrophoresis determine the size of fragments</h2>
Explanation:
- Through the use of this technique DNA sequences were separated to each other for analysis of DNA in forensic investigation.
- This technique is used in DNA fingerprinting for examination of different cases.DNA is negatively charged molecule is determined through the specific fragment size.
- Size determination of DNA fragments this technique of agrose gel were identify the number of fragments which migrate from one place to another place through measure its distance of migration.
- To generate the standard curve of distance of fragments in electrophoresis with the measurements of distance of migration at x axis and long base pairs of DNA at y axis.
- Determine the length of each fragments through the standard curve graph in which the intersected lines will show the length of fragments to migrate in this technique of DNA separation.
