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.
A gamete is a reproductive cell such as a sperm or egg cell. When the sperm and egg come together and fertilize, a zygote is formed.Sperm move; eggs do not. The gametes, sperm and egg each contain one set (haploid) of the total number of chromosomes necessary for fertilization and that allows the zygote to grow to maturity.The zygote contains all the chromosomes necessary. It is diploid --having both sets of chromosomes.perm move; eggs do not.
