Plant tissue culture technique has provided an efficient selection tool for modern plant breeding. The plant tissue culture is made of different steps and their a procedure for this method. Their are different types of Plant tissue culture technique Tissue Culture: The term tissue culture is commonly used to describe in vitro and aseptic cultivation of any part on a ...

Genetic Engineering Pros and Cons: Genetic engineering is providing one of the most important means by which crop plants will be improved in the future. It has a distinct advantage over recombination of plant genetic material brought about by natural and somatic hybridization because it allows Individual genes to be inserted into organisms into a way that is both precise ...

Sanger method of DNA sequencing is an in-vitro method, which involves in-vitro synthesis of DNA strand complementary to one of the strands of the DNA being sequenced. Sanger sequencing is utilized for determining the nucleotide sequence of DNA. This DNA sequencing method was developed by F. Sanger as the method name suggest it self. The DNA sequencing steps involves random ...

Translocation mutation is also termed as chromosomal translocation, translocation chromosomal mutation, DNA translocation, or simply translocations. Translocation mutation involves the movement of a segment of a chromosome to a new place in the genome. The translocation may occur within a single chromosome. Reciprocal Translocation if the chromosomal translocation occurs between two non-homologous chromosomes. this condition is known as Reciprocal Translocation. ...

Chromosome duplication occurs when any part of the genetic material – A single locus or a large piece of a chromosome is present more than once in a genome. As in deletions pairing in heterozygotes may produce a compensation loop. Chromosome duplication may arise as a result of unequal crossing between synapsed chromosomes during meiosis or through a replication error ...

The chromosome deletion is also termed as (gene deletion, Deletion mutation, Deficiency or deletions) is a chromosomal aberration in which a portion of a chromosome or a part of genetic material (DNA) is lost during the process of replication, that missing piece is referred as Chromosome Deletion or Deficiency. Types of Chromosome Deletions The chromosome deletion or deficiency may be Terminal ...

Polyploidy – Types of Polyploidy In Plants, Differentiate Autopolyploidy and Allopolyploidy Polyploidy is a type of condition in which the individuals contains more than two multiples of the haploid chromosome sets. Those individuals in which this condition is found are called Polyploids. And the phenomenon is referred as polyploidy as above mentioned. If an individual has 3n chromosomes, it is termed ...

Significance of Variation in Chromosome Number – Briefly Describe Endopolyploidy And Define Gene Redundancy Variation in chromosome number study has enhanced our knowledge of evolution. Monosomy and trisomy in both plants and animals have made it clear that the diploid genome expresses genetic information in a delicate balanced way. In humans, this equilibrium of genetic expression is much important as ...

Euploidy In Genetics – Differentiate Haploid and Monoploid, Give Methods For Production of Haploids Euploidy is a condition where one or more full sets of chromosomes are in an organism. The euploids may be Monoploids, Diploids (normal organisms) Polyploids. Haploid and Monoploid Difference A distinction should be made between monoploidy and haploidy. Monoploids can be distinguished from haploids as they ...

What is Aneuploidy – What Does Aneuploidy Mean and Define Down Syndrome Aneuploidy can be either due to loss of one or more chromosomes or due to addition of one or more chromosomes. It leads to variation in number of chromosome and do not involve the whole set of the chromosome. The nuclei of the aneuploids contain chromosomes whose number is not ...
