The word genetics, coined by William Bateson, is derived
from the Latin word genesis, which means birth. Genetics is the study of
heredity and variation. Heredity refers to the transmission of genetic
information, more precisely genes, from parents to offspring. This PDF

This note covers the
following topics: quantitative versus qualitative genetics, Hardy-Weinberg law
for gene frequency stability in large populations, Relationship and inbreeding,
Estimation of breeding values, Inbreeding, crossing and bred structure,
Chromosomes and chromosome aberrations, Genetics on hair and coat colour in
mammals, Estimating- and biotechnology and disease resistance.
The objective of this note is have a
greater awareness and appreciation of classical and molecular genetics with
emphasis on genetic material and its formation, transmission, function and
organization. Topics covered includes: historical perspective of genetics,
inheritance patterns and the chromosomal basis of heredity, sex chromosomes in
sex determination and sexual dimorphism, cells reproduce through DNA and nucleic
acids, DNA transcribes into RNA that ultimately translates into protein,
prokaryotic and eukaryotic genes, genetic basis of cancer and how it relates to
the cell cycle.
This lecture note discusses the principles
of genetics with application to the study of biological function at the level of
molecules, cells, and multicellular organisms, including humans. Topics covered
includes: structure and function of genes, chromosomes and genomes, biological
variation resulting from recombination, mutation, and selection, population
genetics, use of genetic methods to analyze protein function, gene regulation
and inherited disease.

This lecture note covers the following
topics: Mendelian inheritance, Mendelian genetics, Meiosis and the Chromosome
theory, Gene mapping, Mutations and mutagenesis, Cytogenetics, Gene regulation,
Genetic interaction, Population genetics, Genetic diseases, Developmental
The first Section
of this book provides readers with background and several methodologies for
understanding genetic disorders. Genetic defects, diagnoses and treatments of
the respective unifactorial and multifactorial genetic disorders are reviewed in
the second and third Sections.
This book aims to provide an overview on
some of the latest developments in several genetic diseases. It contains 14
chapters focused on various genetic disorders addressing epidemiology, etiology,
molecular basis and novel treatment options for these diseases.
This note covers the following topics: Children

inheritance, Genes are real things, cells arise from pre-existing cells, Sex
cells, Specialized chromosomes determine gender, Chromosomes carry genes,
Evolution begins with the inheritance of gene variation, Mendelian laws apply to
human beings, Genetic organization and control.
