Triploid trout are created by forcing the egg to retain a chromosome that is normally ejected during egg development. ... Using pressure treatment at a specific time in the egg development, the polar body and chromosome is retained. With 3 chromosomes the fish is sterile and cannot reproduce.
How do you make triploids?
The triploid seeds are obtained by crossing a fertile tetraploid (4n) plant with a diploid (2n) plant. When you buy seedless watermelon seeds, you get two kinds of seeds, one for the fertile diploid plant and one for the sterile triploid.
Why are triploids sterile?
Although polyploids are common among plants and some animals, polyploidization often causes reproductive failure. Triploids, in particular, are characterized by the problems of chromosomal pairing and segregation during meiosis, which may cause aneuploid gametes and results in sterility.
