Which of the following disadvantages applies to tissue culture?
Correct answer: D. All of the choices are correct
- A. Clone may be genetically unstable
- B. Clone may be infertile
- C. Clone karyotype may be altered
- D. All of the choices are correct
Explanation
Clones produced through tissue culture may sometimes exhibit genetic instability. Genetic instability refers to changes in the genetic makeup of an organism over time, leading to variations in traits or characteristics. When using tissue culture to produce clones (genetically identical plants), there is a possibility that the karyotype, or the number and structure of chromosomes, may be altered. This alteration can occur due to various factors during the tissue culture process, such as somaclonal variation, which refers to genetic changes that arise spontaneously in tissue culture-derived plants. Clones produced through tissue culture may sometimes exhibit genetic instability. Genetic instability refers to changes in the genetic makeup of an organism over time, leading to variations in traits or characteristics.

About Reproduction
Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
