Examples
“Professor Heer has not ventured to identify any of this vast assemblage of Miocene plants and insects with living species, so far at least as to assign to them the same specific names, but he presents us with a list of what he terms homologous forms, which are so like the living ones that he supposes the one to have been derived genealogically from the others.”
“Comparing aligned positions in homologous protein sequences two different behaviors are found:”
“With the help of Evans, they both set up ES cell culture for use in homologous recombination experiments.”

“We knew there's a mechanism called homologous recombination, that biology uses to repair DNA, that can put pieces together.”

“They are called homologous because they have similar parts in similar relations.”
“Mr. Lankester also adduces the close resemblance of the parts on the right and left sides of the body, and in the successive segments of the same individual animal; and here we have parts commonly called homologous, which bear no relation to the descent of distinct species from a common progenitor.”

“All new formations built of cells which continue true to the parent type we may call homologous new formations; while those which depart from the parent type or undergo degenerative changes we may designate heterologous.”
“Scientists have developed a successful test for another type of manipulation called homologous blood doping.”
“The protein produced by the Brca1 gene participates in an important DNA repair pathway called homologous recombination (HR).”
“The gene content and gene order of LyxyMNPV were similar to those of LdMNPV, with 151 ORFs identified as homologous to those reported in the LdMNPV genome.”
