theory of inheritance การใช้

• Other theories of inheritance preceded his work.
• The foundation of this doctrine was based on the theory of inheritance of acquired traits.
• In Germany, first place went to an article on the Chromosome theory of inheritance.
• The experimental work of the German biologist August Weismann resulted in the germ plasm theory of inheritance.
• As a result of her research, Stevens provided critical evidence for Mendelian and chromosomal theories of inheritance.
• The Mendelian theory of inheritance declared that genetic traits and attributes were passed from one generation to another.
• Weismann proposed the germ plasm theory of inheritance, which held that hereditary information was carried only in sperm and egg cells.
• Charles Darwin developed a theory of inheritance he termed pangenesis, from gemmule " to describe hypothetical particles that would mix during reproduction.
• In the meantime, a variety of theories of inheritance ( based on pangenesis, orthogenesis, or other mechanisms ) were debated and investigated vigorously.
• This groundbreaking work led E . B . Wilson in his classic text to name the chromosome theory of inheritance the " Sutton-Boveri Theory ".
• Hurst adopted the chromosome theory of inheritance whole-heartedly referring copiously to Thomas Hunt Morgan's " Drosophila " work, and he was also clearly a staunch Darwinist.
• Darwin himself proposed a theory of inheritance of acquired characteristics which was founded on the notion of " gemmules ", which in his usage referred to the transmission of genetic information from cell to cell.
• In the modern era, Lamarck is widely remembered for a theory of inheritance of acquired characteristics, called soft inheritance, Lamarckism or use / disuse theory, which he described in his 1809 " Philosophie Zoologique ".
• He came close to rediscovering Mendel's particulate theory of inheritance, but was prevented from making the final breakthrough in this regard because of his focus on continuous, rather than discrete, traits ( now known as polygenic traits ).
• In 1932, Durham published the results of a long-term experiment into the genetic effects of alcohol on guinea pigs, conducted at NIMR . This was one of several studies that discredited the Lamarckian theory of inheritance that Stockard's work appeared to support.
• In his famous textbook " The Cell in Development and Heredity ", Wilson linked together the independent work of Boveri and Sutton ( both around 1902 ) by naming the chromosome theory of inheritance the Boveri Sutton chromosome theory ( the names are sometimes reversed ).
• The idea that germline cells contain information that passes to each generation unaffected by experience and independent of the somatic ( body ) cells, came to be referred to as the Weismann barrier, and is frequently quoted as putting a final end to theory of inheritance of acquired characteristics.
• However, the experimental work at his lab with the common fruit fly, " Drosophila melanogaster ", which helped establish the link between Mendelian genetics and the chromosomal theory of inheritance, demonstrated that rather than creating new species in a single step, mutations increased the genetic variation in the population.
• Thomas Hunt Morgan and his assistants later integrated Mendel's theoretical model with the chromosome theory of inheritance, in which the chromosomes of cells were thought to hold the actual hereditary material, and created what is now known as classical genetics, a highly successful foundation which eventually cemented Mendel's place in history.
