The cell commonly called the egg or ovum is more correctly called?
The egg or ovum is more correctly called an oocyte. It is referred to as an oocyte until it is fertilized by sperm, after which it becomes an embryo.
Which cell contributes genetically to the zygote?
Both the egg (oocyte) and the sperm contribute genetically to the zygote. The egg carries half of the genetic material (23 chromosomes) and the sperm also carries the other half (23 chromosomes), resulting in a total of 46 chromosomes in the zygote.
When a primary oocyte divides a secondary oocyte and what are produced?
A primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte undergoes meiosis II to produce a mature ovum (egg) and another polar body.
Why is a zygote form?
A zygote is the single cell that forms when a sperm fertilizes the egg. A zygote forms because a sperm cell fertilizes an egg cell.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.

What goal does a sperm have?
Sperm fertilizes the woman's egg cell.
After a sperm fertilizes and egg what is the egg called?
A fertalized egg is a zygote.
When a primary oocyte divides a secondary oocyte and what are produced?
A primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte undergoes meiosis II to produce a mature ovum (egg) and another polar body.
Why is a zygote form?
A zygote is the single cell that forms when a sperm fertilizes the egg. A zygote forms because a sperm cell fertilizes an egg cell.
What is a fertilized oocyte called?
A fertilized oocyte is called a zygote. This single cell is formed when a sperm cell successfully fertilizes an egg cell, combining their genetic materials. The zygote undergoes several divisions and developmental stages before eventually forming an embryo.
When the primary oocyte divides a secondary oocyte and what else is produced?
The primary oocyte divides into a secondary oocyte and a polar body during meiosis I. The secondary oocyte then goes through meiosis II to produce a mature ovum (egg) and another polar body.
What is a good sentence using sperm and egg in the same sentence?
The sperm fertilised the egg.
Are you more likely to have a boy if the father's family are all boys?
It is the sperm that fertilizes the egg that will determine the sex of your baby. Some sperm carry the X-chromosome and some sperm carry the Y-chromosome. If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy.
Which of the following can be fertilized to produce a zygote?
Secondary oocyte
