The ratio of numbers of chromosomes in human zygote and a human sperm is? ​

Answer»

roductive CELLS contain only half the number of chromosomes as COMPARED to the normal body cells of an organism. The HUMAN sperm and egg have 23 chromosomes each. So when they fuse TOGETHER, the ZYGOTE formed has 23+23=46 chromosomes. So the required ratio is 46 : 23, i.e., 2 : 1.
