A diploid cell has two sets of chromosomes in it. A sperm is the male cell that carries chromosome for reproduction. When the sperms meets with the egg the chromosomes come together to make a baby and it has the full genetic makeup.
Normally non-identical twins.
They would be fraternal twins. Identical twins are created when one sperm fertilized one egg, and hat egg then splits in two. Identical twins are always the same gender, while fraternal twins can be either gender, or a mix of the two.
yes it is possible the sperms and eggs are combined sexualy via two types internaly and externaly
production of male hormone testosterone; and production of sperm
sperms and egg cells
of course millions go in at once but only 1 can go into an egg unless the egg is separated then it could be 2 3 4 5 or however many times the egg is separated or there could be more than 1 egg

50% Sperms fertilizing the egg have two types of sexual chromosomes (y) and (x) and the egg has only one and it's (x). A boys is XY and a girl is XX so with a little bit of math a boy's chance is 1/2 :)

They are known as 'twins'. Identical twins are when 1 fertilised egg divides and each half develops separately in the womb, sharing the same genes. Non-identical twins are when two eggs are fertilised by two separate sperms.
There are two types of twins. Fraternal twins are produced when two eggs are released and two separate sperm fertilize them. These twins are not identical, although they may still look alike because they are siblings.Identical twins are produced when one egg is fertilized by one sperm. During the zygote stage, the egg splits into two. This creates two separate embryos and thus the children will be identical copies of each other. The same exact chromosome match.
It Just Happens In The Women. It Is When 1 Egg Parts Into Two. That's Why They Are Identical Twins.
During pig reproduction, the mother passes two types of cells along. Genetic information from the mitochondria and the nucleus are passed to the piglets.
Identical twins are two children born of one egg and one sperm, that splits early on and then separates, each half then developing into a full organism. Since they came from only one egg and one sperm, their genes will be identical. Fraternal twins are two children born of two eggs and two sperms, each of them developing into a full organism. Since they did not come from only one egg and one sperm, their genes will be different. They could even be opposite sexes.
