Sex cells have 1/2 the number of chromosomes of a normal cell (23)
Adult= 6-20 Child= 5-18 Elderly Adult (60+) = 8-23
A normal karyotype will show all 23 chromosomes at normal growth, and the end will show an either XY (boy) or XX (girl). Karyotypes of people with autosomal diseases and other diseases associated with chromosomes will show abnormalities on that certain chromosome. For example, Down syndrome is caused by a whole extra chromosome on chromosome 21. This extra chromosome can be seen on the karyotype.
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
Haploid cells, as opposed to diploid cells. Haploid cells contain only 23 chromosomes, but normal diploid cells contain 46 chromosomes.
Is 24 days interval normal in menstruation cycle
When you get your period isn't determined by the date on the calendar, it depends on your menstrual cycle (the number of days between your periods) - anything up to a weeks variation from one cycle to the next is normal.
On average, the menstrual cycle (oestrus) of a female goat occurs approximately every 17 to 23 days.
Yes, breastfeeding affacts the menstrul cycle and slows down the cycle. That is why, a woman can give maximun birth of children is 23 in his average period of life if she breastfeed each children for atleast 6 months. ied_kamlesh@rediffmail.com
Woman can always get pregnant unless if she or her partner is sterile. It's during the beginning of the cycle and end of the cycle that the chances of becoming pregnant skyrocket.
Most health care providers will tell you there is no real safe day because there is always a slight chance you can become pregnant, if your cycle is not always regular.Ovulation (fertile period) occurs about 14 days before your period starts, so first, you must know the duration of yourmenstrual cycle: the first day of your last menstrual period (first day of bleeding) to the first day of your next menstrual period. This is the duration of your menstrual cycle.The duration varies from woman to woman, it averages between 25 and 33 days.Ovulation occurs nears the middle of the cycle for most women, day 8 to day 21 (depending on the duration of your cycle).One week before and one week after the approximate day of ovulation is considered to be your fertile period.The days before and after the fertile period is called the safe period. If your cycle is every 30 days, your fertile period runs from day 9 until day 23. Days 1 - 8 and 24 - 30 would be considered your "safe period". (Remember sperm can survive in the female reproductive tract for up to a week!)Because illness, stress, dieting and emotions can throw off the fertile period, this method is not highly recommended for women who do not want to become pregnant. Learning more about your cycle; cervical mucus changes, changes to the cervix, etc, is a much safer and effective means of natural family planning.

That would make your estimated conception date June 1st 2011. However, this date is give or take a few days. It also depends on the length of your menstrual cycle.
None. Every country has the same length day. The only time a day is ever 23 hours is when the first day of daylight-saving begins, and then it is brought forward 1 hour, technically making it the only 23-hour day of the year. Then when it returns to normal time at the end of daylight saving there is a 25-hour day to compensate.
You can count backwards 14 days and that is the time of ovulation. When you have a short cycle like this you ovulate around day 9 instead of day 14 as typical with a woman with a 28 day cycle. Get an average if you can of the past 6 months to see if all the cycles are the same. If they are than you can plan intercourse for the day before or of ovulation for the best chance of conceiving.
Probably not, it depends on the breed and temperatures outside.
It about 20 degrees Celsius on a normal day, 23 on a good sunny day, but 17 on a rainy day, even though in Italy it hardly rains
