Principles of inheritance: Mendel’s laws

Reasons for Hereditary

Heredity is the transmission of characteristics from one generation to the next. It is the most important process in the development of life and is the basis for the transmission of traits that are both beneficial and detrimental. This is one of the fundamental concepts of biology as it explains how living things are related […]

Law Of Independent Assortment

Assortment According to the Law of Independent Assortment It was Mendel’s experimental investigation of the pattern of heredity that marked a watershed moment in the history of the genetics discipline. The results of Mendel’s work led him to propose three rules of inheritance. Mendel’s Law of Inheritance is the fundamental principle of inheritance in genetics,

Principles of Inheritance and Variation

Mendel gave 3 laws of inheritance that supported his observation: Law of Dominance: One among the alleles is dominating and one of the trait gets its presence over another traits with the same characteristic,just in case of the heterozygote, e.g. once we cross homozygous tall (TT) and dwarf (tt) plants, within their child we have

Polygenic Inheritance of Skin Pigmentation

Multiple-gene inheritance (also known as polygenic inheritance, multigenic inheritance, or quantitative inheritance) is a type of non-Mendelian inheritance that differs from a single-gene inheritance, which is the fundamental concept of Mendelian inheritance. An individual polygene is one of a group of non-epistatic genes that interact additively to influence a particular trait, thereby contributing to multiple-gene

Polygenic Inheritance in Plants

Polygenic inheritance, in its most basic form, refers to a character or phenotypic trait that is controlled by multiple genes. It is a type of quantitative inheritance in biology in which two or more independent genes have an additive effect on a single phenotypic trait. Polygenic inheritance is defined as quantitative inheritance in which multiple

Law of Segregation of genes

Mendel, Gregor Johann, was a German scientist who is widely regarded as the “Father and Founder of Genetics.” Between 1856 and 1863, Mendel conducted a large number of experiments on the pea plant (Pisum sativum). He looked into the results of the experiments and came up with a slew of observations. As a result, the

Joule’s Law

Introduction: In electrical engineering, Joule’s law is a mathematical explanation of how quickly resistance in a circuit converts electrical energy to heat energy. In 1840, English physicist James Prescott Joule established that the amount of heat generated per second in a wire carrying a current is proportional to the electrical resistance of the wire and

Incomplete Dominance and Codominance

Gregor Mendel was a master of keeping things simple. During Mendel’s research on pea plants, he discovered that each gene had just two possible alleles, and that these alleles had a good, clear-cut dominance relationship (with the dominant allele completely overcoming the recessive allele when it came to determining the look of the plant). Currently,

Historical Occurrences

Reinterpreting a historical account is known as historical revisionism in historiography. It typically entails opposing the orthodox (established, accepted or traditional) ideas held by academics regarding a historical event, time period, or phenomenon, presenting countervailing evidence, or reinterpreting the reasons behind the persons who made the decisions. As a result of the historical record being
