deficit in language comprehension or production due to brain damage, usually on the left hemisphere (similar deficit not usually found with damage to the right hemisphere)
The only exception is sperm or eggs which are produced by a different type of cell division called ________. meiosis. fertilization. sperm and egg unite to form a single cell called the zygote which contains chromosomes from the sperm and egg. The zygote undergoes mitosis to begin the development of the embryo which eventually becomes a baby
They produce sperm cells that contain either an X chromosome or no sex chromosome, which is designated as O. The females are XX and produce egg cells that contain an X chromosome. If an X sperm cell fertilizes an egg, the resulting zygote will be XX or female. If a sperm cell containing no sex chromosome fertilizes an egg, the resulting zygote will be XO or male. Sex Chromosomes Z-W
