PPT-Allopolyploid Allopolyploid refers to the contribution of two different species to a polyploidy

An example of a Allopolyploid is a liger Its a combination of a lion and tiger and is usually sterile cannot reproduce When two polyploidy organisms mate they create a new hybrid polyploidy organism that differs from either parent The hybrid is usually sterile because the haploid set of chromosomes from this species cannot pair during meiosis with the haploid set of another species.

To remember them, fauna sounds similar to fawn, indicating it refers to animals, whereas flora sounds like flowers, indicating it refers to plants.. Yuvaraja’s College . University of Mysore, Mysore. 11 September 2020. www.hbmahesh.weebly.com. 1. Mitotic and meiotic divisions are highly precise as a result of which the chromosome number of different species are highly stable. But a low frequency of irregularities do occur. These irregularities in chromosome number (some type) have contributed to crop evolution and (all the types) are of much use in plant breeding.. Mutation refers to sudden heritable change in the phenotype of an individual. In the molecular term, mutation is defined as the permanent and relatively rare change in the number or sequence of nucleotides. In other words, mutations arise due to change in DNA bases. The change in the nucleotide may involve replacement of one .
