Human Reproductive System - In human beings, sexual reproduction takes place. Sexes are separate and hence they are known to exhibit sexual dimporphism. Males have sex organs called the tetes while the females have sex organs called the ovaries. Even in the e..

Question : What are the chances of the sperm reaching the egg during sexual reproduction in humans?
Answer : it's hard to calculate the "chance" when there are too many variables affecting it.. it depends on the strength of the ejaculation....like how far the sperm has to travel before it reaches the egg, etc. then there's the healthiness of the sperm to consider, and the health of the female, the female's ovarian cycle,any medication that might affect chances of fertilization. too many factors for an estimate...

Question : The evolution reproduction undergoes from the first living organism to the way humans reproduce. Whoever says something on asexual to sexual steals the best answer
Answer : Here is a really *broad* overview of the phases in the development of reproduction, from asexual reproduction, to full gender-specialized sexual reproduction as practiced by mammals (like humans). I say this is a broad overview, because it's hard to cover almost 3 billion years of development in a Yahoo Answers post. ( :-) ) Note: The following is not a strict sequence ... one step doesn't *have* to evolve to completion before the next begins. Also, in each step I list the advantages for the development, the things that cause it to take hold in natural selection, and improved in many different ways. 1. Asexual reproduction (mitosis). Single-celled organisms (haploid ... a single copy of genetic material) ... just reproduce by cell division ... mitosis = first replicate genetic material, then cell divides. Advantages: Fast reproduction. Doesn't need mates. 2. Bacterial conjugation. Exchange of segments of genetic material. This is not sexual reproduction because it is only *.... More from Yahoo Answers
