the quality of Bulla walnut is better than the others by selection and comparison,which is suitable extension on a country scale.Taking multiple selection method,97 superior individual plants are selected among 127 superior individual plants.Based on analysis of the effects of stereo climate in snow...
How many chromosomes are in a normal human cell and in a human gamete? How many autosomes and sex chromosomes do normal human haploid and diploid cells have? How many chromosomes does a human receive from its mother? How many chromosomes are there during metaphase?
How many chromosomes are in a zygote? How many diploid cells do humans have? Which human cells never have 23 pairs of chromosomes? How many chromosomes are involved in synapsis? How many chromosomes are present after cytokinesis? How many chromosomes are there in...
which have evolved independently many times throughout the tree of life1,2,3. Often these chromosomes differ dramatically in morphology and gene content4,5,6. In mammals, males have a large, gene rich X-chromosome and a degraded, gene poor Y-chromosome, while females ...
the bipolarisation of prophase I nucleus in males of entelegyne spiders: bivalents form two groups at opposite sides of the nucleus. Prior to formation of the metaphase plate, each bivalent is encased in a double membrane tube, which extends nearly to the spindle poles....

Human chromosomes during metaphase. Credit: Steffen Dietzel/Wikipedia Women with Alzheimer's live longer than men with the disease, and scientists at UC San Francisco now have evidence from research in both humans and mice that this is because they have genetic protection from the ravages of the...
Previous studies of the structure of metaphase chromosomes have relied heavily on electron micrography and have revealed the existence of a 10-nm unit fiber that is thought to generate the native 23-30-nm fiber by higher order folding. The structural relationship of these metaphase fibers to the...
