Genetics of Polyploids | Vegetable Breeding

Polyploids are defined as organisms with other than 2 basic sets of chromosomes, that is, monoploids, triploids, tetraploids, and various aneuploids. Segregation in polyploids differs from that in diploids due to the many different ways in which the chromosomes can pair in a polyploid and due to larger number of alleles segregating at each locus. Judging by the frequency with [...]

Independent Assortment of Genes | Vegetable Breeding

After reading this article you will learn about the principle of independent assortment of genes. Independent assortment is defined as random distribution of alleles to the gametes that occurs when genes are located on different chromosomes. The distribution of one pair of alleles is independent of that of other genes located in non-homologous chromosomes. This principle, is as a matter [...]
