In prophase I of meiosis, the homologous chromosomes variety the tetrads. In metaphase I, these pairs line up at the midway stage amongst The 2 poles with the mobile to sort the metaphase plate.
Tetrad only happens through the prophase in the meiosis I soon after pairing of homologous chromosomes. Meanwhile, chromatid pair happens right after undergoing DNA replication throughout the S stage on the mobile cycle.
Tetratype can be a tetrad containing four different genotypes, two parental and two recombinant. A spore arrangement in ascomycetes that includes two parental and two recombinant spores suggests just one crossover amongst two connected loci.

Tetrad refers to the four-aspect construction that sorts in the course of the prophase of meiosis. It includes two homologous chromosomes, and every composed of two sister chromatids. In the meantime, chromatid pair refers to 1-50 % of two similar threadlike strands of the replicated chromosome.
