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 resulting products of meiosis, or gametes, are haploid because each has only one set of chromosomes, and as a result, half the number of chromosomes as the diploid parent germ cell. In humans, diploid cells in the body have 46 chromosomes or 23 pairs (2 copies for chromosomes 1-22 and 1 pair of sex chromosomes). One set of 23 chromosomes is inherited from the mother and the other set is inherited from the father.
