A student is explaining to her colleague the different methods that are available for genetic mapping. Which one of the colleague's following statements indicates a need for further teaching?
A) "I know that linkage studies are rooted in the exchange of genes that occurs during meiosis."
B) "Gene dosage studies involve the measurement of enzyme activity as a reflection of genetic activity."
C) "If hybrid cells were stable, somatic cell hybridization would not be viable."
D) "In situ hybridization focuses on genes that can express themselves in cell culture."

Question

Quizplus · Accepted Answer

In situ hybridization examines genes that do not express themselves in cell culture. The rationale for linkage studies exists in the genetic exchange of genes that occurs during meiosis, and gene dosage is a reflection of gene activity. Somatic cell hybridization necessitates the fact that hybrid cells degrade during division.
