The number of **linkage groups** in a species equals:

  1. The diploid chromosome number
  2. The haploid chromosome number
  3. Twice the diploid number
  4. The number of autosomes only
Show answer and solution

Correct answer: B. The haploid chromosome number

Each homologous pair shares one set of linked genes, so linkage groups = haploid number. **Examples:** garden pea has 7 pairs of chromosomes ⇒ 7 linkage groups; Drosophila has 4 ⇒ 4.
