Ecologist has proposed following explanation to lead biodiversity at tropic.
a) Higher productivity in the tropics allows for more species
b) Environments are more stable and predictable in the tropics, with fairly constant temperatures and rainfall levels year-round
c) Predators and pathogens limit competition in the tropics, which allows more species to coexist
d) High evolutionary speed at tropic than temperate

#Unit 8. Inheritance Biology
Plant height of wild Solanum nigrum is controlled by four pair of polygene. A plant genotype AaBBCcDd with 150 cm height but B plant genotype aabbccdd with 125 cm height present in their population. Following some plants with genotype AABBCCDD, AaBbCCDD, AabbccDD, aaBBccdd and their expected height in cm respectively is
