Genetic Drift- Definition, Types, Examples
Genetic drift can be defined as the loss of alleles from a population by chance. It is one of the four elements that influence the evolution of a gene pool, along … Read more
Genetics is a branch of natural science that deals with heredity due to the transmission of genes, gene regulation, and gene manipulation.

Composition of Gene An entire gene is made up of four distinct nucleotide bases, which are the fundamental units of DNA. The four bases that can be found in DNA’s … Read more
Gene flow is the transfer of genetic material from one population to another or simply a gene migration. Natural selection, genetic drift, and gene flow all work together to create … Read more
There are 23 pairs of chromosomes in each human cell and hundreds of thousands of distinct genes on each chromosome. An individual inherits two versions of each gene, known as … Read more
Inheritance, often known as Heredity, is the process of passing on traits from one generation to the next, either through gametes, sperm, and ova in sexual reproduction or by asexual … Read more
Austrian monk, Gregor John Mendel laid the foundation for genetic studies as until the 1800s, genetics was not introduced as a scientific discipline. He conducted his study relying on the … Read more
Epistasis is the interaction between two non-allelic genes where the phenotypic expression of one gene is masked or suppressed by the expression of one or more other genes. Earlier, Mendelian … Read more
In the semiconservative model of DNA replication, two copies of the original DNA molecule are produced, each copy containing one original strand and one newly synthesized strand. In addition to … Read more
Codominance is a type of inheritance in which the expression of the two alleles (dominant and recessive) of the same gene results in the appearance of both traits in an … Read more
Chiasmata (singular: chiasma, from the Greek, meaning “X-shaped cross”) is the point of contact that occurs in the Prophase I pachytene phase and links two non-sister chromatids belonging to homologous chromosomes together until … Read more
