" The effects of this phenomenon in the genus Brassica may be visualized with the "Triangle of U." This phenomenon can be induced using chemicals such as oryzalin or (*) colchicine.
Diagonal lines on syntenic self-self dot plots reflect the presence of this phenomenon. Peaks appearing in the time distribution of the synthetic substitution rate, or K-sub-s, can be used to detect widespread historical instances of this phenomenon. This phenomenon may cause certain features to be elongated or enlargened in a result referred to as the "gigas effect." The effects of this phenomenon in the genus Brassica may be visualized with the "Triangle of U." This phenomenon can be induced using chemicals such as oryzalin or (*) colchicine. This phenomenon is responsible for many instances of speciation in ferns and angiosperms, and can be used to produce seedless fruit. Endoreplication is one way in which this phenomenon may occur, and it sometimes occurs because of irregularities in prophase I of meiosis. For 10 points, name this phenomenon in which cells possess multiple pairs of homologous chromosomes.
Diagonal lines on syntenic self-self dot plots reflect the presence of this phenomenon.
