1 Multiple Choice 1 point Which of the following best describes the definition of a homologous structure? Anatomical or structural features that exhibit similarities and are inherited from a common ancestor. DNA sequences that produce similar amino acids Anatomical or structural features that share a similar function but do not originate from a common ancestor Having two identical alleles for a trait, such as two dominant alleles. or two recessive alleles.

## Step 1<br />The question is asking for the definition of homologous structures. Homologous structures are anatomical or structural features that exhibit similarities and are inherited from a common ancestor. This concept is a fundamental principle in comparative embryology and evolutionary biology.<br /><br />## Step 2<br />The other options provided do not accurately define homologous structures. DNA sequences that produce similar amino acids are related to the concept of genetic code and protein synthesis, not homologous structures. Anatomical or structural features that share a similar function but do not originate from a common ancestor are considered analogous structures, not homologous. Having two identical alleles for a trait, such as two dominant alleles or two recessive alleles, is related to genetics and inheritance patterns, not homologous structures.
