| | Induced Masu Salmon Spawning of Diploid Females by Triploid Males |
 | | A triploid or diploid male was placed in an aquarium with an ovulated diploid female, and the behavior of male fish was observed. | | | In this study, sexual behavior of triploid males of masu salmon was observed to determine whether males show quivering, a typical courtship behavior of salmonids, and if this behavior would induce spawning behavior and oviposition of diploid females. | | | Sexual behavior of triploid males of masu salmon (the Amago strain, Oncorhynchus masou rhodurus) was observed to determine whether they showed quivering, a typical courtship behavior of salmonids, and if this behavior could induce spawning behavior and oviposition of diploid females. |

| | The Utility of the Diploid Map in Alfalfa Improvement |
| | These studies all conclude that annual medics have potential in these areas, but that further studies are needed to identify more desirable genotypes. | | | Finally, the tetraploid map constructed by Brouwer and Osborn (1999) had only 4-9% segregation distortion, due to tetrasomic segregation and the low recovery of homozygous recessive individuals. | | | Diploid germplasm has been used in the development of several tetraploid alfalfa cultivars. |

| | Diploid Fixation |
| | The conclusions of some studies may be tempered by this fact, so this is important to keep in mind. | | | Thus the reality is that fixation of diploids may be considerably slower if the population of alleles going into a constriction is very diverse. | | | I present this example now, however the degree of difference and effect on study of human genes is going to be much more obvious when we study true haploids (Haploid, Single sex passed loci). |

| | Alternation of Generations |
| | These single cells fuse to form the zygote which will develop into another diploid animal. | | | Whatever variation in details there may be from one organism to another, these two activities must occur alternately if sexual reproduction is to continue. | | | A haploid set of chromosomes, and hence a single set of genes (one genome), is sufficient to control cell function in these organisms (but not in most animals). |

| | Inbreeding and Sex Determination |
| | Haploid individuals have only one allele at the locus (they are hemizygous) and develop as normal haploid males, but if a diploid individual is homozygous at the sex locus, it develops as a diploid male. | | | Diploid individuals that are heterozygous at the sex locus develop as females. | | | When studied, diploid males have been found to be inviable, or unable to mate properly. |

| | Diploid Advantages |
| | For example a goldfish has a diploid # of 188 does that make it more advanced than corn whose # is 20. | | | With more genetic research we are finding that much of disease is the result of genetic damage which is passed along to offspring and cannot be 'undone' by genetic recombination with genetic material from the other parent. | | | If the presence of a "B" option is available, it might be the expression which can tide the organism over a period when the environment does not favor other genetic expression. |

| | (A gamete is a sperm or ovum or their plant equivalents.) One set is haploid, 2 is diploid, 3 is triploid, 4 is tetraploid, 5 is pentaploid, 6 is hexaploid, etc. Any individual with more than 2 sets of chromosomes is said to be a polyploid. | | | Ploidy refers to the numbers of sets of chromosomes an individual or gamete has. | | | The difference between a tetraploid amphidiploid and a diploid, however, is that a diploid has 1 pair of every gene, whereas the tetraploid amphidiploid has 2 pairs of every gene. |
