Cybrids (Cytoplasmic hybrids) are produced by the fusion of:

  1. Two genetically identical cell nuclei
  2. Two separate diploid mesophyll cells from a mature leaf
  3. A haploid egg cell and a sperm cell
  4. A normal protoplast and an enucleated protoplast
Show answer and explanation

Correct answer: A normal protoplast and an enucleated protoplast

Cybrids contain the nuclear genome of one parent but the cytoplasm (including organelles like chloroplasts and mitochondria) of both. This is achieved by fusing a functional protoplast with an enucleated one.
