Which scientists was the first to suggest that growth of cancerous cells was a result of abnormal chromosomes?
maks197457 [2]

Answer:

The correct answers are B and C. Walter Sutton and Theodor Boveri were the first to suggest that growth of cancerous cells was a result of abnormal chromosomes.

Explanation:

The chromosomal theory of inheritance is a scientific theory that relates chromosomes with the transmission of inheritable characters. It is also called the chromosomal theory of Sutton and Boveri in honor of the two people who independently developed it in 1902, Theodor Boveri and Walter Sutton. This theory states that the alleles, the Mendelian genetic factors, are on chromosomes.

Theodor Boveri and Walter Sutton independently developed the chromosome theory in 1902, Boveri, studying embryonic development in sea urchin and Sutton in this work on meiosis in grasshopper.

Sutton and Boveri's proposition in 1902 that chromosomes are the factors of Mendelian inheritance was controversial until its demonstration in 1915 by the work of Thomas Hunt Morgan in the Drosophila melanogaster fly.
