How do you preserve genetic diversity of plants?
Genetic diversity is a very important issue in agriculture. Gene banks store cells from various species in liquid nitrogen that can later be used to preserve the gene pool of an endangered species. A good example of this principle is in the growing of barley. Barley has a narrow genetic base, which leads to vulnerability to disease and pests. Since 1900, no more than 20 sources of germplasm have contributed to the varieties that make up the majority of US barley acreage. This concerns growers and breeders because of two recent warning signs: since 1994 two barley head blight epidemics that have caused billion dollar losses to farmers. Efforts are being made by the North American Barley Genome Mapping Project to build maps of barley germplasm to introduce resistance to the blight into the US barley germplasm base. Over 1,000 loci have been placed on these maps, showing where on the DNA traits such as malting quality, winter-hardiness, and disease resistance are located.
How do you cross breed carnivorous plants?
First, u must make sure that both the flowers you picked up are at the stage of receptive, meaning the ovule can accept the pollen for fertilization.Secondly, u decide which of the two to be the male and female source of the germplasm. Roses are hermaphrodite plant, meaning both sexes, male and female organs are present on the same flower.Having decided that, u remove the pollen of the flower that u decided to be the female. This is done before the flower anthesis, i.e. before the gyneseum or the ovule matured. Cover the flower with paper or cloth.As for the other flower which u had decided to be the male flower, leave it as it is.When the pollen is matured, pick them up and inoculate them on the stigma of the female flower.If the base of the female flower is swelling, it means that your cross is successful. It it drops, your cross is a failure.In plant breeding, this cross is called controlled crossing.Otherwise, what u do is, wait until the two flower about to open, usually very early in the morning, just rub the two flowers together and hopefully there will be some pollen crossing into the other flower. However, u may expect some 'selfing' or self pollination to occurred as well. Both flowers will develop into fruits with some seeds inside them.What u do next is, let the two fruits develop, harvest them when they are ripe, and grow the seeds.When the seedling matured, and baring flowers, u can see a lot of variation among the progenies, ie through selfing and cross pollination.Good luck.
Who is the father of tissue culture?
Gottlieb Haberlandt is credited as the "father of tissue culture" for his pioneering work in 1902 on the concept of plant cell culture and regeneration. His research laid the foundation for the development of modern techniques in tissue culture.
What are the methods of germplasm conservation and which is the best?
The methods of germplasm conservation include seed banks, field gene banks, in vitro conservation, cryopreservation, and DNA banks. The best method depends on the type of germplasm being conserved, as well as factors like cost, long-term viability, and ease of access. A combination of methods is often used to ensure comprehensive conservation of germplasm.

What is germplasm conservetion and its techniques?
Germplasm conservation refers to the preservation of genetic material of plants or animals to ensure their diversity and long-term survival. Techniques used for germplasm conservation include cryopreservation, in vitro tissue culture, field gene banks, and seed banks. These methods help maintain genetic diversity, facilitate breeding programs, and ensure the availability of valuable genetic resources for future use.

Somatoplasm and germplasm are not differentiated in protozoans?
That is correct. Protozoans do not have distinct somatic and germinal cell lines like multicellular organisms. Instead, they typically have a single cell that performs all necessary functions for the organism.

Why some diseases are hereditary?
it is because there is a change in the genetic make up which get inherited to next generation or there is a change in the stomataplasm but not in germplasm
