Question

State whether the following statement is true or false.

The number of linkage groups is greater in Drosophila than in human beings.

Answer 1

This statement is false.

Explanation:

Drosophila has 4 linkage groups, which correspond to its 4 chromosomes, whereas human beings have 23 linkage groups corresponding to their 23 pairs of chromosomes. The number of linkage groups equals the haploid chromosome number of the organism, so humans have more linkage groups than Drosophila.
