Computer-aided Design And Drafting (CADD) Definition - What does Computer-aided Design And Drafting (CADD) mean? Computer aided design and drafting (CADD) is a subfield of engineering which deals with the design and drafting of objects and materials through the use of specialized software that visualizes designs as modular 3D computer models.
gamete. Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
Formation of Gametes : Letâs begin with a summary of reproduction in animals. In animals, meiosis results directly in the formation of gametesâthe reproductive cells, egg and sperm. The successful union of an egg and a sperm is called fertilization, and the resulting cell is called a zygote. The zygote contains genetic material donated from both parents, and is genetically distinct from either.
