Who gave the 'chromosomal theory of inheritance'?

Read the paragraph given below and answer the question.
Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried. Sutton united the knowledge of chromosomal segregation with Mendelian principles and called it the chromosomal theory of inheritance. Following this synthesis of ideas, experimental verification of the chromosomal theory of inheritance by Thomas Hunt Morgan and his colleagues, led to discovering the basis for the variation that sexual reproduction produced. Morgan worked with the tiny fruit files, which were found very suitable for such studies. They could be grown on simple synthetic medium in the laboratory. They complete their life cycle in a short span of time and a single mating could produce a large number of progeny flies. Also, there was a clear differentiation of the sexes the male and female flies are easily distinguishable. Also, it has many types of hereditary variations that can be seen with low power microscopes.
Which statement is incorrect with respect to Drosophila.

What kind of immunity is provided to the infant by colostrum?

Identify the autosome-linked recessive disorder.

If \(a_{i j}\) represents the element of \(i^{\text {th }}\) row and \(j^{\text {th }}\) column and \(A_{i j}\) is the corresponding cofactor, then for the matrix \(A=\left[\begin{array}{ccc}1 & -1 & 0 \\ 2 & 0 & 1 \\ 3 & 4 & 2\end{array}\right]\) the value of \(a_{11} A_{21}+a_{12} A_{22}+a_{13} A_{23}\) is:

If \(A = \begin{bmatrix} 1 & 0 \\ -1 & 5 \end{bmatrix}\) and \(I = \begin{bmatrix} 1 & 0 \\ 0 & 1 \end{bmatrix}\), then the value of k so that \(A^2 = 6A + kI\) is given by:

match List - I with List - II

List - I	List - II
(A) \(\tan ^{-1}\left(\frac{2}{11}\right)+\tan ^{-1}\left(\frac{7}{24}\right)\)	(I) \(\frac{3 \pi}{4}\)
(B) \(\tan ^{-1} 2+\tan ^{-1} 3\)	(II) \(\pi\)
(C) \(\tan ^{-1} 1+\tan ^{-1} 2+\tan ^{-1} 3\)	(III) \(\tan ^{-1}\left(\frac{1}{2}\right)\)
(D) \(\tan ^{-1}\left(\frac{1}{7}\right)+\tan ^{-1}\left(\frac{1}{13}\right)\)	(IV) \(\tan ^{-1}\left(\frac{2}{9}\right)\)
