Isogametes

An isogamete is a gamete that has the same set of chromosomes as another gamete, but differs in shape or size. The isogametic type of gametes is found in some species of animals and plants, where both gametes have the same size and shape, but are different in genetic composition.

For example, in some plants, both types of gametes may be isogamous, meaning that they have the same size, shape, and genetic makeup. This allows them to pair up when fertilized, creating new combinations of genes and providing diversity in their offspring.

Isogametes can also be found in animals such as insects and fish. In some fish species, both types of gametes are isogamite, allowing them to produce offspring with different combinations of genes.

Overall, isogametes represent an important mechanism of genetic diversity that allows for the creation of new gene combinations, which is essential for the evolution and survival of species.
