DEFINITATION & KEY POINTS OF APPLICATIONS OF GENETICS IN PLANT IMPROVEMENT

Botany 1 Comment

TERMS	DEFINITIONS
Hybridization	The crossing of different varieties of plants species is called hybridization.
Transgenic plants	The plants with foreign DNA are called transgenic plants.
Genetic variability	The amount by which individuals in a population differ from one another due to their genes. rather than their environment is called genetic variability
Mutation	The changes to the genetic material (either DNA or RNA) are called mutation.
Splice site mutation	In this case, the coding region of a gene may alter splicing of the mRNA (splice site mutation).
Frameshift mutations	These mutations cause a shift in the reading frame.
Amormphic mutations	When the allele has a complete loss of function (null allele) it is often called an amorphic mutation.
Genetic recombination	Genetic recombination is the transmission‑ genetic process by Which the combinations of ---------------------------- ---------------------------- alleles observed at different loci in two parental individuals become shuffled in offspring.
Mutagens	A Mutagen is a substance or agent that induces heritable change in cells or organisms.
Selection	The process by which certain traits or gene are selected due to sonic environmental advantage is called selection.
Variety	A population of plants that differ consistently from the typical form of the species, occurring naturally in a geographical area is called plant variety.
