GENERAL HISTOLOGY

Detailed explanation-1: -The head of the sperm cell contains the male’s genetic information that is to be passed on to the next generation. Normally, the head of a sperm cell contains one copy of each chromosome .

Detailed explanation-2: -The egg cell provides genetic information from the mother, and the sperm cell provides genetic information from the father. When the genetic information from the parents combines together during fertilization, a genetic blueprint is created in the nucleus of the fertilized egg that is the “DNA blueprint”.

Detailed explanation-3: -The head of the sperm contains the DNA, which when combined with the egg’s DNA, will create a new individual. The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg. The midpiece contains the mitochondria which supplies the energy the tail needs to move.

Detailed explanation-4: -While other normal human cells have 46 chromosomes (or 23 pair), gametes contain 23 chromosomes. Chromosomes are long threadlike structures found in a cell nucleus that contain genetic material known as deoxyribonucleic acid (DNA).

Detailed explanation-5: -How Do Genes Pass From Parent to Child? To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes.
