23 but when a sperm cell meets the egg the egg gets 23 genes from the mom and 23 from the dad then the baby will have 46 chromosomes all together
A human body cell has 46 chromosomes. Female egg cell has 23 chromosomes.
Further Explanation:
Sexual reproduction is the major method of reproduction in a variety of microscopic organisms. It almost includes all the plants and animals. The main process in sexual reproduction is:
Fertilization is a process of the fusion of gametes which are sperm and egg results in the diploid zygote. In meiosis ploidy level of germ cell get halved. Meiosis involves crossing over in between the non-sister chromatid of the homologous chromosome thus leads to genetic variation.
After fertilization, meiosis occurs and crossing over takes place which transfer the genetic information from parents to offspring. The human cell consists of 46 Chromosomes. Therefore, the female egg cell would have a set of 23 chromosomes. Also, the male have a set of 23 chromosomes. By fertilization they give rise to a set of 46 chromosomes in the offspring.
