Detailed explanation-1: -Somatic chromosome doubling of a diploid inter-specific hybrid produces an allotetraploid containing two diploid genomes from two different species. In allotetraploids, the homologous chromosome from each parental species pairs during meiosis and leads to normal meiosis and fertile gamete production [60, 62, 63, 76].
Detailed explanation-2: -If the individual has an even number of chromosome sets, they are usually fertile. This is because the chromosomes can still pair up during meiosis and produce functional gametes. This explains why most naturally occurring polyploids have an even number of chromosome sets.
Detailed explanation-3: -Colchicine is an important mutagen that works by preventing the microtubules formation and doubles the number of chromosomes.
