A woman's egg supply peaks before she herself is born, with at least 7 million eggs packed into the fetal ovary. By birth the number dwindles to a million, and then drops to 300,000 by puberty, And not all matures.
Unlike men, who produce new sperm daily throughout most of their lifetime, women are born with all their eggs in their ovaries. To be more precise, a woman is born with about one to two million immature eggs, or follicles, in her ovaries.
Throughout her life, the vast majority of follicles will die through a process known as atresia. Atresia begins at birth and continues throughout the course of the woman's reproductive life. When a woman reaches puberty and starts to menstruate, only about 400,000 follicles remain. With each menstrual cycle, a thousand follicles are lost and only one lucky little follicle will actually mature into an ovum (egg), which is released into the fallopian tube, kicking off ovulation. That means that of the one to two million follicles, only about 400 will ever mature.
Relatively little or no follicles remain at menopause, which usually begins when a woman is between 48-55 years of age. The remaining follicles are unlikely to mature and become viable eggs because of the hormonal changes that come along with menopause.
a couple thousand maybe 4 thousand..just a guess or less
Each egg cell is a single haploid cell.
Twenty-three chromosomes are in a cell that is formed from a sperm and egg cell.
An egg has one cell. The nucleus inside the yoke is considered a cell.
No, each egg cell is a single haploid cell. Once it is fertilised it divides into many different cells, which later on forms the foetus.
the smallest egg cell is fish egg cell

there are approximately 69 in a sperm cell and approximately chickens in an egg
a liver cell wil be diploid and an egg cell will be haploid (ie half of what a diploid cell has) so there would be 10 chromosomes in the egg cell

One because the sperm is one cell and the egg is one cell
There can be only one.
the smallest egg cell is fish egg cell
Shrimp have 254 chromosomes, so an egg cell would have 127 chromosomes
There are 8 chromosomes in an onion egg (or gamete) cell.
