Arborjet > Diseases > Anthracnose. Anthracnose (leaf blight) is a fungus that winters on twig tissue on the tree. In the spring, spores are transported to new buds and shoots. The disease is enhanced by cool, wet conditions. Infected leaves develop tan to reddish brown lesions that extend along the veins of the leaf.
These tables give the total number of chromosomes (including sex chromosomes) in a cell nucleus. For example, human cells are diploid and have 22 different types of autosome, each present as two copies, and two sex chromosomes. This gives 46 chromosomes in total.
The absolute number depends on the parent organism, but there are half the number of chromosomes present in a haploid cell as compared to the parental diploid cell. In humans diploid cells have 46 chromosomes, and haploid cells have 23. A diploid chromosome Set is a Paired Set; the haploid chromosome Set is a complete set of the Organism's chromosomes - UNPAIRED, as in Unique.
