Question

In some large groups of plants, including dandelions, oaks, and willows, the biological species concept is complicated because the process of _____ allows gene flow to occur between _____ that can be easily distinguished based on appearance.a. hybridization; ecological species

b. polyploidy; evolutionary species
c. allopatric speciation; ring species
d. polyploidy; ring species
e. hybridization; morphospecies

Answer 1

Hybridization; morphospecies.

Option E is correct.

Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization).

Morphospecies: This refers to taxonomic species based wholly on morphological differences from related species.

The above processes (Hybridization and morphospecies) makes the biological concept of large plants complicated.
