How many chromosomes are in a human sex cellUploader: Jaxon 25 days ago Subscribe 3934
Symptoms include failure of the sex organs to normally mature, which may lead to infertility, small breasts and no menstruation; short stature; a wide, shield-shaped chest; and a wide, webbed neck. However, sometimes during meiosis a pair of chromosomes doesn't split so the offspring has an extra, or a missing chromosome. Humans have 22 of these chromosome pairs, called autosomes. Each cell receives a chromosome carrying the same traits from both parents, which then forms a pair. Symptoms include tall stature, speech delays, premature ovarian failure or ovarian abnormalities, and weak muscle tone — although many girls and women exhibit no symptoms. In case of mitosis the division takes place after duplication of the fibres but in case of meiosis the 46 chromatin are reduced into 23 chromatins and during the time of fusion of the two gametes egg cell and sperm the number 46 is maintained.
