<span>Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells.

Assortative mating is the evolutionary mechanism that changes genotype frequencies but does not change allele frequencies.
Assortative mating is the type where two individuals mate with each other on the basis of their similarities and dissimilarities. This is a different phenomenon than the random mating that occurs by chance. Assortative mating can be used to increase the number of organisms of a population containing a certain trait.
Allele is the alternative form of a gene. It arises due to mutations. A gene can have more than one types of alleles. However, usually a gene only has one allele. The alleles are found at the same location of the homologous chromosomes.
