Question

Linkage groups (1) have genes, which were linked together in a single chromosomes (2) show independent assortment (3) do not show independent assortment (4) in prokaryotes are more than one

• A. 1, 2 and 3 are correct.
• B. 1 and 2 are correct.
• C. 2 and 4 are correct.
• D. 1 and 3 are correct.

Answer 1

Answer: (D)

All the linked genes of a chromosome form a linkage group. Because, all the genes of a chromosome have their identical genes on the homologous chromosome, therefore, linkage groups of a homologous pair of chromosome are considered as one. The number of linkage group of a species corresponds with haploid chromosome number of that species. Linkage groups are more than one in prokaryotes.
