8. What is the term given to a duplicate specimen of original type?
a) Lectotype
b) Holotype
c) Isotype
d) Neotype

Explanation: A nomenclature type is a particular specimen of an organism to which its scientific name is attached. Type should be placed in a museum or herbarium research collection. Isotype is duplicate of holotype, the holotype is an original specimen.
9. Phenetic classification does not distinguish between homologous and analogous characters.
a) True
b) False

View Answer
Explanation: Homoplasy is the character share between two species which arises due to convergent evolution. It is a display of phylogenetic character. Wings of birds and bats show homoplasy.
