Germplasm is essentially the living genetic material, such as seeds, tissues, or cells, that is maintained for breeding or conservation purposes. It represents the genetic diversity of a species. Statement 1 (genetic resources) is the overarching definition. Statements 2 (seeds or tissues for breeding) and 3 (egg and sperm repository) are examples of how germplasm is stored and used. Statement 4 (a germ cell's determining zone) refers to specific cytoplasmic regions in some organisms that determine the fate of germ cells, which is a different concept from germplasm.
The Germplasm is required for the propagation of plants and animals. Germplasm is the : 1. genetic resources 2. seeds or tissues for breeding 3. egg and sperm repository 4. a germ cell’s determining zone Select the correct answer using the code given below :

- An irregular mode of reproduction resulting in the development of an embryo without fertilization is called 1. Parthenogenesis 2. Apogamy 3. Sporophytic budding Select the correct answer using the code given below.
- Parthenogenesis: Development of an embryo directly from an unfertilized egg cell. 2. Apogamy: Development of a sporophyte (embryo) from any gametophytic cell other than the egg (e.g., synergids, antipodal cells) without fertilization. 3. Sporophytic budding (or Adventitious embryony): Development of an embryo directly from diploid sporophytic cells (like nucellus or integument) without the formation of gametes or fertilization. If "sporophytic budding" refers to this, then all three processes result in an embryo without fertilization. 41. Which one of the following animals lays eggs to reproduce?
