Humans have 23 pairs of chromosomes. A pair is made up of one chromosome from the egg, and one chromosome from the sperm. That makes it 50-50%.
half
The egg cell or ovum contains genes contributed only by the mother. During fertilization, the egg cell combines with a sperm cell, which contributes genes from the father, to form a zygote with genetic material from both parents.
sperm main function is to carry the male genes to the egg
the sperm cell
Any chance you're doing the BSB yr9 science homework? Back to the topic...Genes are found in the head of the sperm cell and about the egg cell...No clue LOL
your genes you get from your parents when your being formed in your mothes stomach/womb which is formed by your fathers sperm cell when it enters the vajina. BTW i'm eleven
No, as one half of a baby's genes must come from an egg cell and the other half must come from a sperm cell.
process of pregnancy
there are 23 chromosomes in an egg and sperm cell these then combine
The male produces sperm cells, which carry his genes. The sperm cell meets an egg cell from the female which carries her genes. The sperm cell penetrates the egg's outer layer. This is called "fertilizing" the egg. Normally, the outer layer of the fertilized cell thickens, so no more sperm cells can enter it. The fertilized egg then travels to the woman's uterus, where it attaches to the wall of the uterus and ultimately develops into a fetus.
DNA is a double stranded structure, made of two strands. child's get his DNA from his parents, which is made up of one mother's strand and one father's strand. this is how the child get characters of both the parents
no of course not. cancer is caused by a mutation in a cell that spreads and not in a sex cell witch is how genes are passed on.
