Those who wish to adopt the textbooks are required to send a request to NCERT, upon which soft copies of the books are received. The material is press-ready and may be printed by paying a 5% royalty, and by acknowledging NCERT. [11] The textbooks are in color-print and are among the least expensive books in Indian book stores.

Inborn errors of metabolism form a large class of genetic diseases involving congenital disorders of enzyme activities. [1] The majority are due to defects of single genes that code for enzymes that facilitate conversion of various substances into others . In most of the disorders, problems arise due to accumulation of substances which are ...
Walter Sutton (left) and Theodor Boveri (right) independently developed different parts of the chromosome theory of inheritance in 1902.. The Boveri–Sutton chromosome theory (also known as the chromosome theory of inheritance or the Sutton–Boveri theory) is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material.
Epigenetic mechanisms. In biology, epigenetics is the study of heritable traits, or a stable change of cell function, that happen without changes to the DNA sequence. [1] The Greek prefix epi-(ἐπι-"over, outside of, around") in epigenetics implies features that are "on top of" or "in addition to" the traditional (DNA sequence based) genetic mechanism of inheritance.

Genetics is the scientific study of inheritance. [67] [68] [69] Mendelian inheritance, specifically, is the process by which genes and traits are passed on from parents to offspring. [29] It has several principles.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
where n 11, n 12, n 22 are the observed numbers of the three genotypes, AA, Aa, and aa, respectively, and n 1 is the number of A alleles, where = +. An example Using one of the examples from Emigh (1980), [ 7 ] we can consider the case where n = 100, and p = 0.34.
Classical genetics is often referred to as the oldest form of genetics, and began with Gregor Mendel's experiments that formulated and defined a fundamental biological concept known as Mendelian inheritance. Mendelian inheritance is the process in which genes and traits are passed from a set of parents to their offspring.
