Question
Which of the following characterizes parthenogenesis?
AAn individual may change its sex during its lifetime
BSpecialized groups of cells may be released and grow into new individuals
CAn egg develops without being fertilized
DBoth members of a mating pair have male and female reproductive organs
Hard Open in App Solution Verified by Toppr
Correct option is C)
Parthenogenesis, a reproductive strategy that involves the development of a female gamete (sex cell) without fertilization. An egg produced parthenogenetically may be either haploid (i.e., with one set of dissimilar chromosomes) or diploid (i.e., with a paired set of chromosomes). Parthenogenesis has received considerable attention as a tool for the production of stem cells. The possibility of deriving stem cells from parthenogenetic embryos could eliminate the requirement to produce and destroy viable embryos and may reduce the ethical concerns surrounding stem cell research.So the correct option is 'an egg develops without being fertilized'.
