Gametes are hiploid cells.What do you think would happen if the gametes forming a zygote are diploid.
If the gametes forming a zygote are diploid instead of haploid, it would result in an abnormality called polyploidy. Polyploidy occurs when an organism possesses more than two complete sets of chromosomes. In most cases, polyploidy is lethal and leads to the termination of the embryo. However, in some instances, polyploid individuals can survive and even thrive.
If the gametes forming a zygote are diploid, it would result in an abnormal condition known as polyploidy. Normally, in sexual reproduction, gametes are haploid, meaning they contain half the number of chromosomes that a diploid cell has. When two haploid gametes, such as an egg and a sperm, combine during fertilization, they form a diploid zygote with a complete set of chromosomes.
In rare cases, errors can occur during meiosis, the process of gamete formation, resulting in diploid gametes. If two diploid gametes (containing a full set of chromosomes) unite to form a zygote, that zygote would have double the normal number of chromosomes.
Polyploidy can occur naturally in some organisms, typically plants, and can have significant effects on their physiology and morphology. In some cases, polyploidy can lead to increased size, vigor, and fertility, which is why it is often exploited in plant breeding. However, in animals, including humans, polyploidy is quite rare and generally not viable. Most organisms have evolved with precise mechanisms to ensure the formation of haploid gametes and prevent the fusion of diploid gametes.
In summary, if the gametes forming a zygote are diploid, it would result in an abnormal condition called polyploidy, which is rare in animals and not typically viable.
