Question

Genetically identical human progeny is produced when an individual

• A. Practices cross fertilization
• B. Produces identical gametes
• C. Undergoes mutation
• D. Practices by breeding without meiosis

Answer 1

Answer: (B)

Produces identical gametes

The production of a new individual organism or offspring from the parents is the result of a process called reproduction which can be sexual or asexual. In the case of sexual reproduction, the offsprings tend to carry the genetic information from both the parents which are contained in genes carried by chromosomes. Sexual reproduction produces offspring that resemble their parents but are not identical to them but asexual reproduction does not involve mixing of genetic information and hence tend to give rise to genetically identical progeny. In the case of human beings, this take place either due to natural cloning where there is the production of identical gametes.
