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 [...]
After reading this article you will learn about the calculation of probability using binomial distribution. Binomial expansion is of great help in solving genetical problems related to probability. If there are 2 events with alternate independent events having probabilities p and q, then in n number of trials, the probabilities of various combinations of events is given by (p + [...]
After reading this article you will learn about the breeding methods in asexually propagated crops. Reproduction which does not involve the union of gametes is known as asexual reproduction. Reproduction in which sexual organs or related structures take part but fertilization does not occur, so that the resulting seed is vegetatively produced is known as apomixis. In those vegetatively propagated [...]
