Question

Hsapl Duplication node Speclation node Mmus1 Hsap2 17. What type of homology (Orthologous or Paralogous) is Hsap2' present between the following pairs: a. Hsapl & Mmus b. Hsapl & Hsap2 c. Hsap3 and Mmus3 d. Mmus2 and Mmus3 Mmus Euahontoglires suprapimates) Mmus3 Schernatic gene tree containing 2 species Hsap and Mmus (numbers point to ditferent genes 18. Darwin never intended to publish his theory of Natural Selection during his lifetime. What event caused him to suddenly hurry into publication? (2 pts.) Mmus3

Explanation / Answer

17.Ans-

a. Hsap1 & Mmus 1- Orthologous

b.Hsap1 & Hsap2- Paralogous; within species

c.Hsap3 & Mmus3- Orthologous; one to many

d.Mmus2 and Mmus3- Paralogous; within species.

                   When a gene is related to a second gene by a common ancestral DNA sequence; then it is called homolog and the homology is separated by a speciation is called orthologous and if separated by a genetic difference within a genome then it’s called paralogous.
