In the male, meiosis takes placeafter puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis. In females, meiosis begins during the fetal stage when a series of diploid cel...

Does synapsis occur in meiosis 2? When does metaphase II happen in females? If nondisjunction occurs in meiosis II, how many of the four gametes will be aneuploid? What is translocation trisomy 21? As a result of nondisjunction in one of the daughter cells of Meiosis II, when the gamete ...
When does fertilization occur in flowers? Fertilisation: In sexual reproduction, fertilization refers to the process by which two haploid nuclei fuse to form a diploid organism. Fertilization creates individuals with unique genetic compliments different from both parents. ...
