Oak Anthracnose. Anthracnose is a general term used to describe diseases that result in a wide range of symptoms including leaf spots, blotches or distortion, defoliation, shoot blight, twig cankers and dieback on many different deciduous trees and shrubs. In most cases, anthracnose does not cause permanent damage to established trees.
1 Germ cells have only half the number of chromosomes as a diploid cell Â­ one of each pair-and are termed haploid (n) . 2  In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. 3  The number of chromosomes is reduced from 46 to 23 during the process of meiosis.
WHAT IS A TRUE EGG? âEggsâ are produced in the ovaries, BUT these are not true eggs yet, and will never complete meiosis (a special type of cell division) and become true eggs unless OR until they are first fertilized by a sperm. Within the ovary, a follicle consists of one potential egg cell surrounded by special cells to nourish and protect it. HOW MANY EGGS DOES A WOMAN ACTUALLY HAVE? A human female typically has about 400,000 follicles/potential eggs, all formed before birth. Only several hundred (about 480) of these âeggsâ will actually ever be released during her reproductive years.
