I will explain, but I don't know why you put this in cat behavior.
The X chromosome and Y chromosome control gender. If an embryo's two chromosomes are XX, it will be a girl. If the chromosomes are XY, it will be male. A pair of chromosomes have to have at least one X chromosome in it, but can also have a Y chromosome.
What else can I help you with?
What does the female sex cell produce?
The female sex cell, also known as the egg or ovum, produces half of the genetic material needed for reproduction. During fertilization, the egg combines with a male sex cell (sperm) to form a complete set of chromosomes for a new individual.
What do you get when you cross a male sex cell with a female sex cell?
When you cross a male sex cell (sperm) with a female sex cell (egg), the result is a fertilized egg, also known as a zygote. This zygote contains genetic information from both the mother and father and will eventually develop into a new organism through the process of embryogenesis.
What part controls the activity of a cell?
The answer is nucleus :)
What happens to the number of chromosomes when two grasshoppers sex cells join in fertilization?
there is a baby
What is the job of cell membrane?
Cell membreneA layer that controls what enters and what leaves the cell. Or a protective covering enclosing the entire cell.(controls substances going in and out of the cell.)
When sex cells combine to produce offspring each sex cell will contribute how many chromosomes?
a baby
What sex cell helps the unborn baby to grow?
The sperm cell enters the womans vaginal area going to the ovary, which fertalizes the womans egg cell, creating and baby.
Why do you commit sex in making baby and it conclution?
because the egg andd the sperm cell meet which makes a baby
What controls a cell?
The Nucleus controls the cell.
What is the cell that controls a substance into and out of a cell?
cytoplast cell it controls a substance into and out a cell.
What does the cell membrane controls?
the cell membrane controls what goes in and out the cell
How baby's sex is determined?
The babies sex is determined by the sperm. The egg has XX chromosome and each sperm cell is either a XX or XY chromosome. So which ever sperm cell reaches the egg and implants determines the sex. If the sperm was an XX chromosome the baby would be a girl, if the sperm was XY chromosome the baby will be a boy. Hope this helps!

What cell controls all the cell?
the nucleus controls all the activity in the cell.
What controls the passage of nutrients in and out of the cell?
The cell membrane controls what enters and exits a cell.
What do you get when you cross a male sex cell with a female sex cell?
When you cross a male sex cell (sperm) with a female sex cell (egg), the result is a fertilized egg, also known as a zygote. This zygote contains genetic information from both the mother and father and will eventually develop into a new organism through the process of embryogenesis.
Which cell part controls the cell's activities?
I think you are talking about the nucleus, which is the "brain" of the cell. It controls everything that cell does.
