One set of 23 comes from mom and the other 23 from dad. The egg and sperm cells are an exception–they have only 23 chromosomes each. A sperm from the man combines with a woman’s egg in her womb to make a zygote. The zygote ends up with a total of 46 chromosomes and can now grow into a baby.
How many different combinations of chromosomes are possible in the sperm?
A sperm cell contains 23 chromosomes with two possibilities for each chromosome. The possible number of sperm cells based on different chromosome combinations is (2)23 = 8,388,608.
How many genetic combinations are possible per child?
There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.
How sperm is genetically different from egg?
Each cell differs genetically from its parents. Fertilization of an egg by a sperm brings the chromosome count to 100%. In the human body, there are no cells (like the Sperm and Egg cells) which are so different and yet cannot do without each other and belong together.
