Gametes must be haploid because?
they need to combine during fertilization to restore the diploid number of chromosomes in the offspring. Having haploid gametes ensures that the resulting zygote has the correct number of chromosomes for normal development.
Why should the gametes be haploid when the new organism will be diploid?
Gametes need to be haploid because when they fertilize and combine during sexual reproduction, they restore the full complement of chromosomes (diploid) in the zygote. This ensures that the offspring will have the correct number of chromosomes for proper development.
Why are the cells at the end of meiosis not ready to act as gametes?
The cells at the end of meiosis are not yet ready to act as gametes because they are haploid, meaning they only have half the chromosome number needed for fertilization. These cells need to undergo one more round of cell division, called cytokinesis, to become functional gametes with a full set of chromosomes.
What is the meaning of a haploid?
Cells with a full set of chromosomes are Diploids. Cells that contain unpaired chromosomes contain half the set of chromosomes and are called Haploids. Gametes are reproductive cells (sperm and eggs) that are haploids which are produced by the process meiosis.
What is the significance of the chromosome number in gametes?
Chromosome numbers in gametes are always half that of normal cell. For example human cells have 46 chromosomes but a human gamete (sex cell e.g sperm/eggs) will have half that number which in this case will be 23. The number is chromosomes is halfed in gametes so that when the sperm meets the egg and the fuse to make a zygote that you get half the genetic material from your Mother and half from you Father, meaning you are not a clone.

Why are gametes haploid?
Gametes are haploid because they need to combine with another haploid gamete during fertilization to restore the full set of chromosomes in the resulting zygote. This ensures genetic diversity and prevents the doubling of chromosomes with each generation.
Why are the cells at the end of meiosis I not ready to function as gametes?
During meiosis I, the cells at the end are not ready to function as gametes because they are still haploid and need to undergo meiosis II to further divide and produce mature gametes with the correct number of chromosomes.

Gametes need to be haploid because when they fertilize and combine during sexual reproduction, they restore the full complement of chromosomes (diploid) in the zygote. This ensures that the offspring will have the correct number of chromosomes for proper development.

Why is it important to have haploid gametes?
To prevent the chromosome number from doubling every generation.Sexual reproduction involves two cells (gametes) combining their chromosomes. The process is fertilization, and the product is a zygote.If each gamete has a single set of chromosomes (as happens in humans, most other animals, and many plants) the zygote will have two sets of chromosomes. Whatever the zygote grows into, whether a person, pelican, or pineapple, every cell in the body will have two sets. If the gametes also have two sets each, the next zygote will have four, and so on, until you need a wheelbarrow to carry your chromosomes around!So every life-cycle that includes a doubling of the chromosome number also includes a halving, and that process is called meiosis. Meiosis occurs at different times in different life-cycles. In humans meiosis happens when the gametes are being formed, but in plants it happens when spores are being formed.
How many chromosomes did the parent cell have diploid or haploid?
To determine whether a parent cell is diploid or haploid, you need to know its chromosome number. A diploid cell contains two complete sets of chromosomes (one from each parent), while a haploid cell has only one set. For example, in humans, diploid cells have 46 chromosomes, while haploid gametes (sperm and eggs) have 23 chromosomes. Therefore, if the parent cell has 46 chromosomes, it is diploid; if it has 23, it is haploid.
How many chromosome' s do people have in their gametes?
People have 23 chromosomes in their gametes – 22 autosomes and one sex chromosome. This is the result of a process called meiosis, which halves the number of chromosomes in a cell to produce gametes with half the genetic material.
Why are gametes haploid cells?
Mammals cannot survive as a haploid cell, and meiosis creates four gametes that are haploid, so the two haploid cells need to combine in order to have a diploid zygote that is also genetically different.
Why do gametes need 12 the number of chromosomes of a regular body cell?
Gametes require half the number of chromosomes of a somatic (regular) cell as gametes are the sex cells. When gametes combine to make a zygote (a fertilised cell), the complete number of chromosomes will be present.
