The tetrad is a structure that only exists during the late stages of Prophase I and early stages of Metaphase I in Mieosis I. Prior to being sent off to different cells, the h â¦ omologous chromosomes clump together in these units called tetrads consisting of 2 chromosomes and 4 chromatids. Corresponding parts of the 2 homologous chromosomes are able to switch with each other during this state in a process known as crossing over.
1.1 Framework silicates (tectosilicates). This is volumetrically the most important group of silicate minerals. More than two thirds of the crust is composed of framework silicates. Each oxygen ion of the SiO 4 tetrahedron is shared with another tetrahedron. Hence, three-dimensional framework forms which gives name to the group.
