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.
Diploid human cells have 2 sets of 23 chromosomes for a total of 46 chromosomes: By Regina Bailey. Definition: A haploid cell is a cell that contains one complete set of chromosomes.Gametes are haploid cells that are produced by meiosis.Examples: The haploid number is the number of chromosomes within the nucleus of a cell that constitutes one complete chromosomal set. This number is commonly abbreviated as n, where n stands for the number of chromosomes.ametes are haploid cells that are produced by meiosis.
