Introduction: The two different modes of reproduction are sexual reproduction and asexual reproduction. The asexual reproduction involves the production of offspring with genes inherited from a single parent. The offspring is genotypically similar to the parent organism. The sexual reproduction involves the fusion of two haploid gametes to form a diploid zygote. Both the haploid gametes are from two different parents and the offspring is not an exact copy of a single parent.
Answer to Problem 1TY
Correct answer: The development of offspring from the unfertilized eggs is called parthenogenesis. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
Parthenogenesis is the property of lower plants and invertebrates, such as insects, some spiders and amphibians. Even some birds reproduce by this method. In this type of reproduction, the egg produced is diploid and develops into a complete organism. This is also a type of asexual reproduction.
Option d. is given as “parthenogenesis”.
Parthenogenesis is the development of offspring from the unfertilized eggs. Hence, the correct answer is option d.
Reason for incorrect answer:
Option a. is given as “budding”.
Budding is a type of asexual reproduction, but this process does not involve the formation of an ovum. Instead, the new organism emerges out of the previously existing organism. Hence, option a. is incorrect.
Option b. is given as, “cloning”.
Cloning refer to the process of generation of genetically identical biological entity or cell. Hence, option b. is incorrect.
Option c. is given as “fragmentation”.
In this type of reproduction, the organism breaks into smaller fragments and each fragment is capable of developing into a complete individual. Hence, option c. is incorrect.
Option e. is given as, “implantation”.
Implantation is a type of sexual reproduction in which the egg is fertilized by sperm and the fertilized egg gets implanted in the wall of the uterus. Hence, option e. is incorrect.
Hence, the options a., b., c., and e. are incorrect.
The type of asexual reproduction in which the development of offspring takes place from unfertilized eggs is called parthenogenesis.
