The presence of selective breeding poses a significant challenge to the theory of natural selection. Answer: D Essential Information (Sentence Simplification) Question In an “Essential Information question”, you will see the question you see an entire sentence highlighted in the reading passage.

As for breeding, gourami types breed by egg-laying, and then the eggs are fertilized, either on the inside through mouthbrooding or on the outside through bubble nesting. Bubble nesting is where the male creates floating layers of bubble, and the female proceeds to lay eggs on them before ...

Triploid individuals often play a key role in speciation by hybridization. An understanding of the gamete types (ploidy and genomic content) and stability of hybrid populations with triploid individuals is therefore of importance for exploring the role o
