Question

Quizplus · Accepted Answer

Homologous genes are those that are derived from a common ancestor and share a similar sequence and function across different species. In this case, since the gene coding for a cardiac glycoside is found in two species of oleander plant, it suggests that these genes are homologous. Orthologs are a type of homologous genes that are found in different species but have evolved from a common ancestral gene, maintaining the same function. This fits the description of the gene in question, making "homologous; orthologs" the correct choice.
