The autosomal complement comprises 15 biarmed and 8 telocentric
pythagoricus show a chromosome complement of 44 telocentric
chromosomes, and 42 telocentric
chromosomes in males of P.
farreri consisted of the following chromosome types: three metacentric (m), four submetacentric (sm), seven submetacentric or subtelocentric (sm-st, centromeric index [+ or -] SD overlaps two categories), four subtelocentric (st), and one subtelocentric or telocentric
(st-t) (Table 1).
In both species, the largest pair is submetacentric, the next four pairs are subtelocentric, and the two smallest pairs are telocentric
marulius has 4 metacentric, 4 submetacentric and 36 telocentric
chromosomes for the Thailand stock, while the Indian stock has 40 metacentric and 4 telocentric
In each of these, the fundamental number (NF) is double the diploid number because no telocentric
chromosomes were observed.
For example, in Acridoidea, with basic telocentric
karyotypes (see below), centric fusions produce neo-XY/neo-XX systems (Fig.
The average size of the 60 pairs of telocentric
(T) monoarm homologous chromosomes that comprise the karyotype of P.
The autosome complement consists in 14 pairs of telocentric
chromosomes and one pair of small metacentric chromosomes.
A = acrocentric; M = metacentric; SM = submetacentric; T = telocentric
un] is located on a telocentric
chromosome that is homeologous to group 4 from Ae.
Essentially, their involvement becomes apparent when a metacentric in one complement is replaced by two acro- or telocentric
chromosomes in another, though that observation does not in itself distinguish between the two processes.
