How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
What would happen if meiosis did not produce sex cell?
The individual would not be able to reproduce sexually.
Where do you get chromosomes from?
The chromosomes in a karyotype are from a sample of body cells.
Example of a sexually influenced trait?
One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.
Do whales produce sexually or asexually?
sexually
An organism that reproduces sexually has a diploid number of 30. How many chromosome will a gamete of this organism have?
15- apex

If meiosis did not occur in sexually reproducing organisms?
If meiosis did not occur in sexually reproducing organisms, the chromosome number would double in each generation. Sexual reproduction results in new combinations of genetic traits.
What do guys like sexually?
Most guys favorite thing to do sexually is HAVE SEX but also a nice blow job form an educated individual might work to.
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)

What does mean when you dream about being sexually involved with a relative?
That you are a very bad, sick individual :P

Is men sexually active in age after 80 years?
Yes, some men remain sexually active in their 80s and beyond. While sexual desire and function may decrease with age, maintaining a healthy lifestyle, communication with a partner, and seeking medical advice for any health concerns can help sustain sexual activity in older age.
When is a cow sexually mature?
Depends on the breed and the individual heifer. Most heifers are sexually mature by the time they are around 15 months of age; others will be sexually mature when they are 24 months of age, like with Brahman heifers.
What age do you girls first get sexually active?
It depends entirely on the individual ! Puberty in girls can happen as young as 8 or 9 years old - or as late as 20. As for being 'sexually active' that is solely the responsibility of the girl.
Why is meiosis important for sexually producing organisms?
Meiosis produce 4 heploid cell and that four cell contain single strand chromosome which is 23 and nt 46 so it give variation and evolution
