The behaviour and structure of the sex chromosomes in spermatocytes of Microtus oeconomus
The meiotic behaviour and structure of the sex chromosomes of Microtus oeconomus (2n=30) in Giemsa stained preparations are described. The X-Y pair appears as a sex vesicle at late zygotene. At late pachytene an ...

A light microscopic study of the development and behaviour of the synaptonemal complex in spermatocytes of the mouse
A method is presented for the sequential analysis of male meiosis using hydroxyurea (HU). HU produces a gap in the spermatogenic line. The front of surviving cells behind the gap was examined day by day using ...

Location and variation of the constitutive heterochromatin in Petunia hybrida
The location of heterochromatin in the chromosomes of Petunia hybrida (2n=14) is presented. C-banded mitotic metaphase chromosomes and carmine-stained pachytene bivalents have been studied. It is shown that the h...

Dosage effect of a gene with a regulating effect on anthocyanin synthesis in a trisomic Petunia hybrida
A Petunia hybrida inbred line (W 28) has white flowers with red spots on the corolla. These spots are the result of back mutations of an unstable allele of the gene Anl for anthocyanin synthesis. Among the progen...
