In this article we will discuss about:- 1. Origin and Occurrence of Triploids 2. Chromosome Pairing and Chiasma Formation in Auto-Triploids 3. Fertility of Auto-Triploids 4. Pneotypic Effects of Auto-Triploidy. Origin and Occurrence of Triploids: (i) Triploids originate from hybridization between auto-tetraploids (4x) and diploids (2x). The autotetraploid produces diploid (2a) gametes which when fertilized by a normal monoploid (x) [...]
The following points highlight the top eight aspects of reciprocal translocation in genetics. The aspects are: 1. Chromosome Pairing 2. Orientation of the Quadruple at Ml 3. Sterility in Interchange Heterozygotes 4. Crossing Over in the Interchange Heterozygotes 5. Detection of Interchanges 6. Isolation of Homozygous Interchange Lines and a few others. Aspects of Reciprocal Translocations Chromosome Pairing Orientation of [...]
The following points highlight the top fifteen uses of translocation in genetics. The uses are: 1. Study of chromosome behaviour during meiosis 2. Assignment of centromere position 3. Interchanges as genetic markers 4. Determination of unknown locus of a gene and chromosome mapping 5. Association of linkage groups or genes to specific chromosomes and a Few Others. Uses of Translocation [...]
