The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 [5] and 1903, [6] as well as to independent work by Theodor Boveri during roughly the same period. [7] Boveri was studying sea urchins, in which he found that all the chromosomes had to be present for proper embryonic development to take place. [8]
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.
These inheritance patterns can also be applied to hereditary diseases or conditions in humans or animals. [ 11 ] [ 12 ] [ 13 ] Some conditions are inherited in an autosomal dominant pattern, meaning individuals with the condition typically have an affected parent as well.
Population genetics is the branch of evolutionary biology responsible for investigating processes that cause changes in allele and genotype frequencies in populations based upon Mendelian inheritance. [3] Four different forces can influence the frequencies: natural selection, mutation, gene flow (migration), and genetic drift. A population can ...
Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.
In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution. James Mark Baldwin and others suggested that an organism's ability to learn new behaviours (e.g. to acclimatise to a new stressor) will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through ...
Conrad Waddington, known as "Wad" to his friends and "Con" to family, was born in Evesham to Hal and Mary Ellen (Warner) Waddington, on 8 November 1905.. His family moved to India and until nearly three years of age, Waddington lived in India, where his father worked on a tea estate in the Wayanad district of Kerala.
Many genetic conditions have varying ages of onset, ranging from an infantile form to an adult form. Genetic counseling can facilitate the decision-making process by providing the patient/family with education about the genetic condition as well as the medical management options available to individuals at risk of developing the condition.
