Question

initial concept of chromosomal basis of inheritance was seen in​

Answer 1

Answer:

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.

Answer 2

The Boveri–Sutton chromosome theory (also known as the chromosome theory of inheritance or the Sutton–Boveri theory) is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material.[1][2][3] It correctly explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors (particles) required by Mendel's laws. It also states that chromosomes are linear structures with genes located at specific sites called loci along them.[2]


Walter Sutton (left) and Theodor Boveri (right) independently developed different parts of the chromosome theory of inheritance in 1902.
It states simply that chromosomes, which are seen in all dividing cells and pass from one generation to the next, are the basis for all genetic inheritance. Over a period of time random mutation creates changes in the DNA sequence of a gene. Genes are located on chromosomes.
