Correct Answer
C. Marker-assisted selection

Explanation
Marker-assisted selection (MAS) represents a cutting-edge approach in plant breeding that leverages genetic markers associated with specific traits, significantly expediting the traditionally time-consuming and resource-intensive breeding process. This technique employs molecular markers, such as Single Nucleotide Polymorphisms (SNPs) or Simple Sequence Repeats (SSRs), to identify and select plants with the desired genetic characteristics.

Rate this question:
8.

What does the term "cisgenic" refer to in crop science?
- A.
  
  Introducing genes from a different species
- B.
  
  Modifying genes within the same species
- C.
  
  Creating sterile plants
- D.
  
  Enhancing cross-pollination resistance
Correct Answer
B. Modifying genes within the same species

Explanation
CRISPR-Cas9, a revolutionary gene-editing tool, has transformed the landscape of crop improvement by enabling highly precise modifications in the DNA of various plant species. This advanced technology operates on the principles of the CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) system, utilizing the Cas9 protein to target and modify specific genetic sequences with unparalleled accuracy.

Rate this question:
9.
