Genetic Controlled Male Sterility

Genetic male sterility (GMS) Genetic male sterility is controlled by some nuclear genes called Male Sterile genes. It has been evident that this type of sterility is usually maintained by recessive genes (barley, mustard, pigeon pea, paddy) and less frequently by dominant genes (safflower). The male sterile allele is m …

Allopolyploidy: Mixing up Different Genomes

Link of other two related artciles 1 and 2. This is number 3. (Polyploidy: A Game with Chromosome Numbers) (Autopolyploidy: Multiplying Same Genome) Allopolyploidy Allopolyploids have two or more genomes derived from different genomically unlike, distinct species are present. For example, 4x = AABB. Two types of genomes are here …

Polyploidy: A Game with Chromosome Numbers

Polyploid Organism bearing the exact multiple of the basic chromosome number (x) of the species. In polyploid cells and organisms, the number of chromosome sets exceeds that of diploid. Depending on the number of chromosome sets, polyploid can be classified as triploids, tetraploids, pentaploids etc. Good to know In potato, …
