They contain only one of each type of chromosome needed, they are known as haploid cells.
they only contain half the chromosomes needed, therefore need one another to create a new organism.

A skin mutation in human skin cells cannot be passed on to another person because these mutations occur in somatic cells, which are not involved in reproduction. Only genetic changes in germ cells (sperm and egg) can be inherited. Therefore, while skin mutations can affect an individual's health or appearance, they do not affect the genetic material that is transmitted to offspring.
AnswerNo, the damp spot contains living sperm cells, but the act of wiping it off your finger and using a spermicidal condom has reduced the probability to < 0.01%. the pregnancy is from another introduction of sperm cells AnswerNo she cant get pregnant that way and honestly if you don't know how a girl gets pregnant you obviously don't need to be having sex. Comment to second answer: There are plenty of people that are ignorant about pregnancy. That still doesn't stop them from getting pregnant. Also, whenever sperm has the potential to make contact with the female reproductive system there is always a chance for pregnancy, no matter how small the odds.
Mercury is one of the five planets visible to the naked eye from Earth. It has been known since ancient times and does not have a specific team or individual credited with its discovery.
nope you see chromosomes. which are each a single tightly wound strand of DNA but you cant make out that out. can see genes at all unless your looking at a sequence or have a florescent or radioactive tag.
Yes, a donkey can get pregnant from horse sperm. Not many people breed animals like this anymore, but that is how people use to get light weighted horses, but it was usually a horse getting pregnant from donkey sperm. Any animal of the same species can get pregnant from each other. For example, a dog and a wolf, a wolf and a coyote, a tiger and a lion, a horse and a zebra, a horse and a donkey, all of these are possible.
a human has 46 chromosomes. a sperm or egg cell is called a haploid, which means that they only have 23 chromosomes. humans can't be haploid. we need all 46 chromosomes and all of their DNA goodness.
no you cant because the sperm from a boy has to touch your vigina and a toy cant give sperm.8==>
K7 labs . Its not made by a person alone . An Anti Virus has 3 parts for it running successfully which cant be coded by one person
