Solution
Answer:
a. All the combinations in the option are homologous to each other as they are sharing the gene
combinatios from common ancestor.
b. First second and last combinations are orthologus combination because, these separate gene
combination of homologous gene arrived through speciation.
c. None of the combinations showing proper feature of paralogue gene sequence,as none of the
combination is showing structural similarities (after speciation, duplication etc,) regardless the
species.
