Question

Since the number of genes in an organism is much larger than the number of pairs of chromosomes, the Chromosomal Theory concludes that:

विकल्प

• Each chromosome pair must contain several genes

• The total number of genes equals the number of chromosome pairs

• Genes are located outside the chromosomes

• Each chromosome pair contains only a single gene

Answer 1

The Chromosomal Theory reasons that because the number of genes in an organism far exceeds the number of pairs of chromosomes, each chromosome pair must carry several genes. This explains why multiple genes are transferred together as linked units on a chromosome.
