When sex cells are produced by a special cell division called meiosis, chromosomes exchange large segments ofDNA. This ensures that each new cell has a unique genetic makeup and explains why, with the exception of identical twins, no two siblings are ever completely genetically alike. These ex...
Remember the zygote? This little ball of cells divides until it contains about 100 cells. Then it becomes known as ablastocyst. The inner group of cells will form theembryo. The outer group of cells forms the placenta, which will provide nourishment. ...
Cells divide and reproduce in two ways, mitosis and meiosis.Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division. ...
