Question

Quizplus · Accepted Answer

Homologous molecular sequences are the best choice for constructing a phylogenetic tree because they are derived from a common ancestor and can reveal the evolutionary relationships between different species. Heterologous sequences may have different origins and thus can be misleading, while analogous sequences may have similar functions but different evolutionary origins, making them less useful for constructing a phylogenetic tree. Heterozygous and homozygous refer to genetic variation within a single organism and are not relevant to constructing a phylogenetic tree.
