Why must the sex cells have half the chromosome number of the normal body cells?

Otherwise, after fertilisation, the number of chromosomes would be doubled. Then, after each generation, the number of chromosomes would continue to be doubled!
One might argue that after fertilisation, meiosis could take place, that is, the halving of the number of chromosomes could take place. It is true, but rare. Some organisms use this method.

How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
What produces with half the normal number of chromosome?
the answer is MEIOSIS meiosis produces 4 single cells with half member of the chromosomes mitosis produces 2 cells with full member of the chromosomes
Is this true that sex Cells have one-half of the number of chromosome Pairs as body -Somatic- Cells have?
Yes it is. Gametic sex Cells have the genetic complement of 1N; somatic Cells are 2N.
How many chromosomes are located in normal human body cells?
The question is somewhat ambiguous as there are literally millions of different species, each with its own cellular chromosome count.In addition, normal Somatic Cells have exactly twice the number of chromosomes that normal Haploid cells have.Below is a list of different species and their corresponding Somatic cell chromosome count.For the Haploid cell chromosome count simply divide the listed Somatic cell number by 2:Somatic Cells - Chromosome CountHuman - 46Common fruit fly - 8Guinea Pig - 64Dove - 78Garden Snail - 54Earthworm - 36Tibetan Fox - 36Domestic Cat - 38Domestic Pig - 38Laboratory Mouse - 40Laboratory Rat - 42Rabbit - 44Syrian Hamster - 44Hare - 48Gorillas / Chimpanzee - 48Domestic sheep - 54Elephants - 56Cow - 60Donkey - 62Horse - 64Dog - 78Kingfisher - 132Goldfish - 100-104Silkworm - 56
What is one member of the chromosome do?
the cells on ur body
How does the number of chromosome in a persons gametes compare with the numbers of chromosomes in the body cells?
There are half as many chromosomes in gametes than in normal body cells.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
How many chromosome do normal human body cells have?
5
Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.
Do Body cells only have half the total number of chromosomes?
All body cells contain a total number of 46 chromosomes except sex cells (the egg and the sperm) which have half the number of chromosomes (23) no.... body cells or somatic cells have 46 chromosomes which is the diploid chromosome number of homo sapiens... gametes or sex cells have 23 chromosomes which is the haploid chromosome number...
If the body cells have 12 chromosomes how many will the sex cell have?
A house fly has 12 chromosome in their body cells and half that number (6) in their sex cells.
Why are the number of chromosomes in egg sperm cells different from the number of chromosomes in other cells of the body?
well, for one they are haploid (n) whereas other cells in the body (somatic cells) are diploid (2n) this means that sperm cells (egg cells for females) only have half the amount of chromosomes as any other cell in the body
How many chromosomes do human egg cells and sperm cells have?
There are 23 chromosomes in a human sperm or egg (ovum).Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number.
How do cells become a full human body?

How many chromosomes are in the egg and in the sperm cells?
Half the number that are in the adults normal body cells
