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.
A diploid has two sets of different DNA.. for example almost all human cells are diploid. There are 46 chromosomes in the human diploid cell. A haploid cell has half of the genetic information of diploid cells. A human haploid cell has 23 chromosomes. These cells are the sperm and the egg. Coming together, each of their 23 chromosomes combine to make a baby with 46 chromosomes.
