In mathematical genetics, a genetic algebra is a (possibly non-associative) algebra used to model inheritance in genetics.Some variations of these algebras are called train algebras, special train algebras, gametic algebras, Bernstein algebras, copular algebras, zygotic algebras, and baric algebras (also called weighted algebra).
His book The Genetical Theory of Natural Selection, published in 1930, over 20 years before the double-helix shape of DNA was discovered, was the first attempt to explain Darwin's theories within the foundation of genetics. [10] Chapter 6 of this book is titled "Sexual Reproduction and Sexual Selection" and includes a genetic interpretation of ...
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
Length of p, q corresponds to allele frequencies (here p = 0.6, q = 0.4). Then area of rectangle represents genotype frequencies (thus AA : Aa : aa = 0.36 : 0.48 : 0.16 ). The different ways to form genotypes for the next generation can be shown in a Punnett square , where the proportion of each genotype is equal to the product of the row and ...
[9] DNA replication. DNA is unwound and nucleotides are matched to make two new strands. If the sequence of the nucleotides in a gene changes, the sequence of the amino acids in the protein it produces may also change—if part of a gene is deleted, the protein produced is shorter and may not work anymore.

The work of Fisher, Haldane and Wright founded the discipline of population genetics. This integrated natural selection with Mendelian genetics, which was the critical first step in developing a unified theory of how evolution worked. [4] [5] John Maynard Smith was Haldane's pupil, whilst W. D. Hamilton was influenced by the writings of Fisher.
Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1 ] [ 2 ] [ 3 ] It is an important branch in biology because heredity is vital to organisms' evolution . Gregor Mendel , a Moravian Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically.
The book is sectioned into four parts. The first part, Genetics and the Scientific Method briefly review the History of genetics and the various methods used in genetic study. The second part focus on Mendelian inheritance, the third part deals with Molecular genetics and the last section deals with Quantitative genetics and Evolutionary ...
