Let’s review the pathways by which the genetic information in DNA is transferred from one DNA molecule to another (the process termed DNA replication) and from DNA to ribonucleic acid (RNA) molecules (called transcription), and then transferred from RNA to a protein (termed translation) by a code that specifi…

In an autotetraploid, only four nulliplex genotypes are possible (a 1 a 1 a 1 a 1 , a 2 a 2 a 2 a 2 , a 3 a 3 a 3 a 3 , and a 4 a 4 a 4 a 4 ), and only one tetragenic is possible (a 1 a 2 a 3 a 4 ).
