X-linkage was discovered for the first time in?
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.

Why was Morgan initially skeptical of Mendel's theories of genetics?
Mutation does not equal speciation( new unchanging species)Morgan realized that one of its genes had been altered and it had produced a new kind of eye. Morgan bred the white-eyed fly with a red-eyed fly and got a generation of red-eyed hybrids. And when he bred the hybrids together, some of the grandchildren were white-eyed. Their ratio was three red to one white. Here was a mutation, but one that didn't fit DeVries's(Mendel's) definition. DeVriesthought that mutations created new species, but the fly that had acquired the white-eyed mutation remained a memberof the same species. It could still mate with other fruit flies, and its gene could be passed down to later generations in proper Mendelian fashion.
How is chromosome gene linkage and exception to the law of independent assortment?
Independent assortment can take place only if genes are located on different homologous chromosomes .Mendel was lucky because 7 traits he studied were located on different homologous chromosomes .Bateson 1906 noted first deviation from Mendles law and it was explained by Morgan . Linked genes can't assort independently as they are transfered en block .
Who develop the gene theory?
Ultimately, Gregor Mendel's statistical approaches to genes, which he called factors, led DeVires, Morgan and other at the turn of the 20th century to develop a theory that explained the workings of genes.
Who are four scientist that worked to better understand DNA?
James Watson, Gregor Mendel, Barbra McClintock and Thomas Hunt Morgan
What is the difference between Morgan Stanley and JP Morgan?
The difference between Morgan Stanley and JP Morgan is that they are both different companies. In 1933 the government decided that retail and investments had to be separate so one of the Morgan family founded Morgan Stanley.
What conclusions did Morgan arrive at with his experiments on fruit flies and why did they extend Mendel's conclusions?
Through his experiments on fruit flies, Morgan found that Mendel's principles applied to organisms and plants, and to humans as well. Thomas Hunt Morgan was an evolutionary biologist.
Whose early work is the basis for much our current understanding of genetics?
Mendel discovered the concept of inheritable traits. Johannsen coined the term gene. TH Morgan identified the gene as a distinct locus. Crick, Watson and Franklin elucidated the 3D structure of DNA.
Who are the seven giants of biology?
Actually there are 10 giants of biology, they are: # Charles Darwin # Louis Pasteur # Alexander Fleming # Edward Tenner # Antoni Van Leeuwenhoek # Robert Hooke # Gregor Mendel # Thomas Morgan # James Watson & Francis Crick # Carolus Linnaeus
What is the difference between an 1894 silver dollar and an 1894 Morgan silver dollar?

What is the price difference between the 1901 Morgan silver dollar and the Morgan silver dollar stamped with an o?
The 1901 Morgan with no mintmark is worth more than the one with the "O" mintmark, but the difference depends on the condition (grade) of the coins. A 1901-O Morgan in the grade of EF-40 has an average value of $29.00 A 1901 Philadelphia (no mintmark) Morgan in the same grade is $105.00.
