Answer Details
Genetic characteristics are passed from the parents to offspring through the gene. Genes are the basic units of inheritance that carry the instructions for the development and function of all living organisms. When a sperm cell from the father fertilizes an egg cell from the mother, they combine to form a single cell called a zygote. This zygote contains all the genetic information from both parents, which is then passed down to all the cells in the developing embryo through cell division. As the embryo grows and develops, the genetic information in the cells guides the formation of all the body's structures and functions. The umbilical cord and placenta are structures that connect the developing embryo to the mother's uterus during pregnancy, but they do not play a direct role in the transfer of genetic information from the parents to the offspring. The cytoplasm is the fluid inside cells, and while it plays an important role in many cellular processes, it does not contain genetic information that can be passed on to offspring.
