Numerous studies based on different approaches have contributed to our understanding of the processes of metacentric formation in the house mouse.
Pairs 1 - 4, 6 and 8 were metacentric, pairs 5 and 7 represented an intermediate between the meta- and submetacentric type of structure.
He depicted, for each type of chromosome (acro-, telo- and metacentric), the distribution of their frequency as a function of their size.
Also, it is not clear why the metacentric clines should widen the further they are from the race centre.
Pairs 1, 3 and 5 had submetacentric type of structure while pairs 2 and 6 were metacentric.
The standard karyotype which consists of only acrocentric (single-armed) chromosomes is modified by the presence of metacentric (bi-armed) chromosomes.
Diploid numbers ranged from 29 to 40 and a total of 36 different karyotypes were found on the basis of metacentric complement.
Therefore, for each metacentric, both length and arm length ratio were estimated.
Pair 4 was intermediate between the metacentric and submetacentric types.
For each metacentric a best-fit cline is shown.
They consisted of 18 metacentric, submetacentric or subtelocentric chromosomes and three acrocentric or telocentric chromosomes.
Once the data on metacentric frequency was collated for each collection site, characteristics of the hybrid zone were determined.
Hence, the question is how the final size of a metacentric can be the factor that explains the greater involvement of acrocentrics of intermediate size in fusions.
A chromosome is metacentric if its two arms are roughly equal in length.
