A Genetic Study of Segregation in a Translocation Heterozygote in Drosophila.
URING meiosis, homologous chromosomes normally pair with each other and separate whereas the members of pairs of non-homologous chromosomes assort independently of one another. This behavior is disturbed, however, in individuals carrying a translocation. It is well known that a t the first meiotic division separation of the four components of a translocation configuration may take place in a nu...

15 صفحه اولDe novo translocation heterozygote with three reciprocal translocations.
An extremely rare case of a child with three balanced reciprocal translocations involving six different autosomes is described. These abnormalities have apparently arisen de novo and seem to have only relatively minor phenotypic effects. The meiotic possibilities are discussed and cytogenetic markers suggest that the damage may have occurred in a paternal gamete.

in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Functional analyses of genetic pathways controlling petal specification in poppy.
MADS-box genes are crucial regulators of floral development, yet how their functions have evolved to control different aspects of floral patterning is unclear. To understand the extent to which MADS-box gene functions are conserved or have diversified in different angiosperm lineages, we have exploited the capability for functional analyses in a new model system, Papaver somniferum (opium poppy...
