Question

A hybrid where the cytoplasm of two parent cells are fused by retaining only one parent nucleus is called

• A. An interbreed
• B. Symmetric somatic hybrid
• C. Asymmetric somatic hybrid
• D. Cybrid

Answer 1

Answer: (D)

Cybrid

Sometimes a cybrid cell is produced when the nuclei of one parent gets eliminated during developmental stages and only the cytoplasm of two cells fuse containing the nucleus of only one parent.

Symmetric somatic hybrids are those which retain the full somatic complements of parental species.

Asymmetric hybrids are those which exhibit the full somatic complement of only one parent while the chromosomes of other parental species are lost during mitotic divisions.

Interbreed is a type of cross between two different species to produce a young one with a mixture of two species.

Thus, the correct answer is option D.
