Answer: The answer is option C) two different species on the basis of reproductive behavior
Explanation:
This situation observed in South America is a good example of Sympatric speciation.
Where, two organisms similar in many respects by
- occurring in the same territory, differing ONLY as two different species because they DO NOT interbreed - thus, becoming different species on the basis of reproductive behavior.
So, option C is the answer
Answer:
Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. ... In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele.
The hydrogen bonding of nucleotides into a new DNA molecule is facilitated by enzymes. Hydrogen bonding is the electromagnetic attraction between polar molecules in which hydrogen is bound to a larger atom, such as oxygen or nitrogen. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pairs forms two hydrogen bonds while the C-G pair forms three. The enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.
