Study Notes
Human Reproduction
- The result of human reproduction is the formation of a zygote, which develops into a fetus and eventually a baby.
Gamete Cells
- Gamete cells, also known as sex cells, have a genetic composition of 23 chromosomes, which is half the number of chromosomes found in somatic cells.
Fertilization
- The merger of the ovum (egg cell) and sperm results in a zygote with a complete set of 46 chromosomes, combining the genetic material from both parents.
- The process of merging two gamete cells into one zygote cell is called fertilization.
Gestation Period
- The fusion of the sperm and ovum during fertilization initiates the 9-month gestation period in human reproduction, during which the fertilized egg develops into a fetus.
