Male and female gametes at fertilization forms a homologs Microscopic observations showed that during fertilization, the unite, providing evidence that genetic material resides in the cell membrane Brightly staining, threadlike bodies within the nucleus were termed of these bodies could be traced through cell division. chromosomes diploid A image can reveal abnormalities in meiosis of eggs and sperm ; the movements gametes contain a single set of chromosomes. The fusion of zygote. the number of chromosomes in daughter cells remains the same as in the the number of chromosomes in daughter cells is half that of Two chromosomes that match in size, shape, and banding when isolated and stained are is an image of an individual's chromosomes arranged in homologous pairs.
