The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 and 1903, as well as to independent work by Theodor Boveri during roughly the same period. Boveri was studying sea urchins, in which he found that all the chromosomes had to be present for proper embryonic development to take place.
Then, over the next few decades, Walther Flemming, Theodor Boveri, and Walter Sutton made a series of significant discoveries involving chromosomes, including what these structures looked like,...
Boveri and Sutton's chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance.
- A chromosome in a diploid organism is hemizygous when only one copy is present. The cell or organism is called a hemizygote. Hemizygosity is also o...
- You may get a white female with a XwXw genotype or a red-eyed female with a XwXw+ genotype. Morgan used this to verify his hypothesis further. Open...
- If the white eye trait was linked to having the Y chromosome, then you would expect that: a) all male offspring of white-eyed males had white eyes,...
- Bridges found rare flies with surprising inheritance patterns: daughters that inherited X-linked traits (like eye colour) only from their mother, a...
- There is no mistake or contradiction. Note the statement preceding it: "He was careful to rule out alternative possibilities" He ruled out that it...
- The first mutant white allele isolated (called w1) arose spontaneously because of transposon insertion. There are now many strains of flies with di...
- Gregor Mendel's work didn't explain co-dominance and so many other factors but was later found out to be the basic building block of genetics.
- The role of the Y chromosome is to determine the sex. As for eye color, nothing.
- If you breed a homozygous red eyed female with a white eyed male, the female offspring will be heterozygous and have one copy of the mutant allele,...
- The previous comment is incorrect, the logic is flawed. If a white eyed female required a white eyed female, you would have an infinite regression....
Apr 22, 2013 · In many ways, Sutton reiterated the work of Theodor Boveri, a German scientist who in the late 1880s and early 1890s observed that chromosome numbers are cut in half as egg cells mature, and concluded that sperm and egg nuclei have half sets of chromosomes.
Oct 31, 2023 · In 1902, Theodor Boveri observed that proper embryonic development of sea urchins does not occur unless chromosomes are present. That same year, Walter Sutton observed the separation of chromosomes into daughter cells during meiosis.
Mar 3, 2011 · In the same years, Walter Sutton of Columbia University came up independently from Boveri with a largely identical conclusion. Therefore, the chromosomal theory of inheritance came to be called also the Boveri-Sutton chromosome theory.

Was Wilson close to Boveri & Sutton?
The German biologist Theodor Boveri independently reached the same conclusions as Sutton, and their concepts are often referred to as the Boveri–Sutton chromosome theory. Sutton's hypothesis was widely accepted by most scientists, particularly cytologists, at the time. [5]
