Predicting our
Future: Genetics and Linear Algebra
The
science of Genetics is a mixture of biology and chemistry. It is the science of the hereditary
evolution of a species over a period of time based upon their chemically
make-up; a.k.a. their DNA. A field
of genetics that is undergoing extensive research today is Population
genetics. The field focuses on the
genetic structure of certain populations, such as humans, and then tries to
scientifically explain the movement of genes from one generation to the
next. Within this field are
several forms of genetic inheritance, but this paper will focus only on two of
these forms: Autosomal inheritance (also known as Mendelian inheritance) and
X-linked inheritance. Both of
these forms of inheritance are found in humans and plant species, but the
methods of gene movement differ between the two. This paper will discuss the mathematics that take place in
both forms of inheritance and provide a brief history of the formation of the
math behind the science. This math
is known as genetic algebra.
Applications of genetic algebra and population genetics to the real
world will also be discussed. The
linear algebra techniques of formation of matrices, solving for eigenvalues and
eigenvectors, and methods of diagonalization of a matrix are used in this
paper. The science of Genetics and
the math behind it provide useful tools that can predict our future based upon
our genetic make-up.
