DEFINITATION & KEY POINTS OF APPLICATIONS OF GENETICS IN PLANT IMPROVEMENT
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 |
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 |
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 |
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. |
