A gamete is a specialized cell that contains half of the DNA of the parent organism. Since the structure of gametes for different species can vary considerably normal would be any gamete that
contains the correct amount of DNA and is capable of fertilization.
If sperm is used as an example, normal would be those sperm that have the correct amount of DNA, are progressively motile and have a morphology(form/structure) that will allow them to fertilize the egg once it is reached.
Haploid (?)
Normal gametes should contain one allele from each gene.
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.
Male gamete in flowers is pollen grain that produce in anther . When male gamete in animal is sperm that produce by testes
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.

Normal gametes should contain one allele from each gene.
The male gamete - spermatozoon and the female gamete - ovum.
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
Human gametes have 23 chromosomes. (In cases of abnormality there may be a different number of chromosomes in a gamete).
There are 23 haploid chromosomes in a normal human gamete (sex cell).
There are 23 haploid chromosomes in a normal human gamete (sex cell).
A normal mouse gamete would have 19 autosomes.
Gametes carry half the number of normal chromosomes as a body cell. Since there are normally 46, this means there are 23 chromosomes in a human gamete.
A gamete is a specialized reproductive cell that contains half the number of chromosomes found in a normal body cell. In humans, the sperm cell produced by males and the egg cell produced by females are examples of gametes.
