The event leading to the combination of an ovum and sperm is called fertilization. It occurs when a sperm penetrates the outer membrane of the ovum, allowing the genetic material from the sperm to join with the genetic material of the ovum. This creates a zygote, which is the first cell of a new individual.

Why only one sperm cell can fertilized an ovum?
Only one sperm cell can fertilize an ovum due to a process called the fast block to polyspermy. Once a sperm cell penetrates the egg, it triggers changes in the egg's membrane that prevent other sperm cells from entering. This ensures that only one sperm cell can successfully fertilize the egg.
What is the name giving to the male reproductive cell that fertilises the ovum?
The male reproductive cell that fertilizes the ovum is called a sperm cell.
When the ovum is fertilized by the sperm this is called?
When the ovum is fertilized by the sperm, it is called fertilization. This process involves the fusion of genetic material from the sperm and the egg to form a zygote, which will eventually develop into an embryo.
The female gamete is called what?
The female gamete is called an ovum or an egg. This is the cell that is fertilized by the male gamete known as the sperm.
How does the ovum prevent multiple penetrations of sperm cells along it's periphery?
The ovum has a protective layer called the zona pellucida that hardens after the entry of one sperm cell, preventing additional sperm cells from penetrating. This process is known as the zona reaction and ensures only one sperm cell fertilizes the egg.
Event leading to combination of ovum and sperm genes?
Fertilization
What is the event leading to the combination of ovum and sperm genes?
fertilization
How many sperm fertilize the ovum?
Typically, only one sperm fertilizes an ovum to form a zygote. Multiple sperm attempting to fertilize the ovum can lead to abnormalities in the resulting embryo.
What is a Sperm Production and what is a Ovum Production?
Sperm production is the creation of sperm in the testies of the bull. Ovum production is the creation of eggs in the ovaries of the cow.
Why only one sperm cell can fertilized an ovum?
Only one sperm cell can fertilize an ovum due to a process called the fast block to polyspermy. Once a sperm cell penetrates the egg, it triggers changes in the egg's membrane that prevent other sperm cells from entering. This ensures that only one sperm cell can successfully fertilize the egg.
What can the ovum become if it joins a sperm?
When the ovum and sperm come together they become a fertlized egg also known as a zygote.
How are a zygote and an ovum different?
Ovum is mainly 1n and zygote formed by fusion of ovum and sperm is 2n ,,,
What does an ovum have that the sperm also has?
Chromosomes.
How many chromosomes does the fertilized ovum contain?
The fertilized ovum, or zygote, contains 46 chromosomes. These come from the combination of 23 chromosomes from the egg cell and 23 chromosomes from the sperm cell.
Explain how the structure of a sperm enables it to reach the ovum?
It has a long tail that helps it swim easily to reach the ovum, It has a pointed tip in the head of the sperm which allows it to effectively enter the ovum.
What is the name giving to the male reproductive cell that fertilises the ovum?
The male reproductive cell that fertilizes the ovum is called a sperm cell.
Which is that sperm that fertilize the ovum?
The luckiest of all sperms makes it alive and fuses with the ovum.
