Which statement about zygotes, which form by fertilization, is correct? A Zygotes have a full set of chromosomes, receiving half from each parent B Zygotes have half the set of chromosomes from one parent only. C Zygotes have two full sets of chromosomes, one set from each parent. D Zygotes have half the set of chromosomes, one-fourth from each parent

A zygote is indeed a fascinating beginning to the journey of life! When an egg and sperm unite during fertilization, they create a zygote that contains a full set of chromosomes, made up of half from the mother (egg) and half from the father (sperm). This unique genetic blend sets the stage for all the genetic diversity and individuality in organisms. Understanding zygotes is more than just a biology lesson; it’s the foundation for reproductive technologies like in vitro fertilization (IVF). In IVF, eggs and sperm are combined outside the body to form zygotes, which are then implanted into the uterus. This process helps countless families overcome fertility challenges and adds a little scientific magic to the miracle of life!
