WebThe reproductive system produces and transports sex cells, also called gametes. The male sex cells are called sperm and the female sex cells are called oocytes. Each sex cell carries one set (s) of genetic instructions and has 23 chromosomes. The new cell formed during fertilization contains 46 chromosomes, similar to most cells of the body. WebFeb 2, 2024 · The male reproductive system consists of sexual organs, accessory glands, and a series of duct systems that provide a pathway for sperm cells to exit the body and fertilize an egg. Male genitalia only equips an organism to initiate fertilization and does not support the development of a growing fetus. Male sex organs include:

Meiosis is necessary for many sexually-reproducing animals to ensure the same number of chromosomes in the offspring as in the parents. The act of fertilization includes two cells fusing together to become a new zygote. If the number of alleles of each gene is not reduced to 1 in the gametes that produce the … See more Meiosis is the process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction. Many organisms package these cells into gametes, such as egg and sperm. The … See more Before meiosis, the DNA is replicated, as in mitosis. Meiosis then consists of two cell divisions, known as meiosis I and meiosis II. In the first division, which consists of different phases, the duplicated DNA is separated into … See more WebSep 4, 2024 · During meiosis, the pairs of chromosomes separate and segregate randomly to produce gametes with one chromosome from each pair.
