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

Answer 1

17)

Orthologs are the corresponding genes in different lineages/species due to speciation.

Paralogs are the result of gene duplication and holds a new function.

a) Hsap 1 &Mmus 1 -- orthologus

b) Hsap 1 and Hsap 2 ---paralogous

c) Hsap3 and Mmus3 ----orthologus

d) Mmus 2 and Mmus 3----paralogus

18) Darwin was relectant to publish his ideas because that they were strongly against the ideas of religious belief . According to Darwin God did not create each species seperately and nature did itself and continues to create new species.

A letter from Alfred Wallace caused Darwin to publish his ideas on The Theory of Evolution.A.Wallce asked darwin to review his paper on evolution by natural selection ,so darwin hurried upon refining his biik "The Origin of Species" and published in 1859 and to receive primary credit before any one else did .
