Question

lease refer to the phylogeny below depicting genes present/absent in different animal taxa ich of the following are examples of orthologous genes? Choanoflagellates o a Sponges A 3 C P Cnidarians Acoelomorphs Protostomes bx P/2 abdA A) genes A and 3 in Sponges B) genes 9, 10, 11, 12, 13, and 14 Echinoderms in vertebrates 12 3 45 678 9 10 11 12 C) gene Antp in Protostomes and Cephalochordates gene 9 in Echinoderms gene Pin Acoelomorphs and gene P1/2 in Protostomes 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Vertebrates E) gene 3 in Sponges and gene FP in Cnidarians 12 3 4 5 6 7 8 9 10 11 12 13 14

Explanation / Answer

D .gene P in Acoelomorphs and gene p1/2 in Prostomes

orthologs are genes that are related by vertical descent from a common ancestor and encode proteins with the same function in different species.
