Introduction:
Offspringare the young ones born from living organisms, which are either produced by one organism or, by two organisms (in case of sexual reproduction). Group of offspring may be more commonly referred to as progeny or brood (for example, chickens hatched from one clutch of eggs, offspring of the honeybee). The egg that is not fused with a male gamete (sperm) is called anunfertilized egg.
Answer to Problem 1TY
The correct answer is option (d) parthenogenesis.
Explanation of Solution
Explanation/justification for the correct answer:
Option (d) parthenogenesis. The development of offspring (or young ones) from an unfertilized egg is called parthenogenesis. The offspring (or progeny) produced by parthenogenesis are generally haploid. For example, some invertebrate animals (like aphids, some scorpions, some bees, some mites, etc.), few vertebrate animals (like some reptiles, fish, amphibians, etc.), and some plants. So, this is the correct option.
Explanation for incorrect answer:
Option (a) budding. It is the form of asexual reproduction. In budding, cells of the parents go through mitosis and form a different type of structure called bud or outgrowth before the new individual is produced. So, this is an incorrect option.
Option (c) cloning. Many organisms produce clones through asexual reproduction. In the process of cloning, individuals are produced either artificially or naturally. Progenies of cloning are genetically identical. So, this is an incorrect option.
Option (e) implantation. Implantation refers to the adherence of the fertilized egg to the wall(or lining) of the uterus, which takes place about 6 or 7 days after fertilization (or conception). So, this is an incorrect option.
Parthenogenesis is thegrowth and developmentof offspring (or progeny) from an unfertilized egg. Hence, the correct answer is option (d) parthenogenesis.
