When an organism's DNA contains a hybrid of two or more sets of chromosomes from different species, this is called Allopolyploid. Heteroploidy: Type # 1. Or in other words each chromosome has two chromatids. Here we report a detailed protocol for targeted genome editing in the model grass Brachypodium distachyon and its allotetraploid relative B. hybridum, describing gRNA. There are some allotetraploid 2EBN wild species with desirable traits for potato improvement. This evidence and that from other relevant hybrids strongly suggest that T. caespitosum is a true allotetraploid with the genome formula JeJeSS. An evolutionary model using diploid and allotetraploid cotton species identified 80 % of non-coding transcripts in allotetraploid cotton as being uniquely activated in comparison with its diploid ancestors. . represent individual chromosomes and n is the haploid chromosome number.
