Question

According to the chromosomal theory of inheritance, the behaviour of ____(A)____ was parallel to the behaviour of __(B)_____.

• A. A-chromosomes, B-genes
• B. A-genes, B-proteins
• C. A-chromosomes, B-proteins
• D. A-genes, B-cell organelles

Answer 1

The correct option is A A-chromosomes, B-genes

Chromosomal theory of inheritance was proposed by Sutton and Boveri.

Sutton and Boveri noted that the behaviour of chromosomes was parallel to the behaviour of genes in the following ways:

Both chromosomes and genes occur in pairs.

Both chromosomes and genes segregate at the time of gamete formation such that only one member of each pair is transmitted to a gamete.

Sutton united the knowledge of chromosomal segregation with Mendelian principles and called it the chromosomal theory of inheritance.
