How to Analyse DNA in Genetic Genealogy

How to Analyse DNA in Genetic Genealogy

DNA has many uses in genealogy, and there are two main ways that DNA is tested in order to create a profile of your genetic make-up. In genealogy, 3 main DNA types are tested and analysed, those DNA types are:

    Autosomal – Distant past, used in ancestrymtDNA – Tests the direct maternal lineY-DNA – Tests male direct paternal line

Two types of test can then be completed on the DNA; STR’s (Short Tandem Repeats), also known as Microsatellites and SNPs (Single-Nucleotide Polymorphism).

STRs are repeating sequences of 2-6 base pairs of DNA. Continue reading How to Analyse DNA in Genetic Genealogy

Introduction to excretion in plants

Excretion is the process of elimination of waste materials from the body. Excretion in plants is much simpler than that of animals and as such it does not pose any serious problem in plants. There are several reasons for this:-

1. The rate of catabolism is comparatively much slower in plants than in animals having the same body weight and consequently the rate of accumulation of body waste is much slower.
