In this article we will discuss about:- 1. Classification of Haploids 2. Origin of Haploids 3. Meiosis. Classification of Haploids: According to their cytological features, haploids have been classified into different types (Fig. 17.1), a brief description of which is given below. I. Euhaploid: The chromosome number of such a haploid is an exact multiple of one of the basic [...]
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 [...]
