Yes that is possible, it has happened twice to me!
In some animals the embryo develops inside the egg. In mammals, the egg and sperm become an embryo that develops into a life form.
Yes they are identical twins.
Identical twins are sometimes formed when one egg after being fertilized by one sperm, divides into two halves.
Embryo twinning is when you have one embryo planted and it splits to make two different sets of cells this is good because both of the cells would have 50% genes from your mother and father.Genes come from your mums egg and your dads sperm which means you will look like them or maybe some of their relatives this is because they would have come from your grandparents and they also gave birth to any of your uncles and aunts this why some people might say to you you look like one of your relatives.
When you have an embryo with two similar parts, this means that there will be identical twins. They are formed when a single egg are split into two. Identical twins will always be the same sex.
During the first two months of pregnancy the unborn child is known as an embryo.
A fertilized egg's yolk provides all of that embryo's nutrient, it also provides protection to the embryo. There are two types of yolk, white yolk and yellow yolk, both having their purpose.
It takes many sperm to break the outer barrier of the egg, but only one to fertilize it. When that sperm meets the egg, their genetic material (chromosomes) combine to form 46 and the fertilized egg, zygote, beings to rapidly divide into a blastocyst. After about two weeks it is called an embryo, and after eighth weeks a fetus. After about 40 weeks, it is born and is called an infant.
Identical twins come from one egg and one sperm. Fraternal twins come from two eggs and two sperm.
it is the action of fertilising an egg with the sperm of a closely related species. Tests are done on the embryos for a period of no more than 14 days (two weeks) and then the embryo must be destroyed.
True. Sperm and egg cells are gametes, and thus are necessarily haploid. These haploid gametes were created through the process of meiosis. When the two fuse to create an embryo, the new embryo will then have 46 chromosomes, the full number for a human. The embryo will receive one copy of each chromosome from each parent. If sperm and egg cells were to have the full set of 46 chromosomes, with both copies of each chromosome from each parent, then when they fused the embryo would have 92 chromosomes total. And the progeny of that embryo would have an even higher number of chromosomes. Having haploid gametes is necessary to maintain the stability of the species.
If a broody chicken pushes away an egg, it can mean two things:The egg temperature is not maintained (it has turned cold)- egg was infertile- embryo diedThe egg is rottenNon-broody chicks will push an egg out of its way because the egg is in its way. Several hens may use the same nest, and some hens do not want to sit on an egg while she is trying to deposit one.
In Angiosperms the pollen tube pierces the wall of the embryo sac and releases two male gametes. One of these male gametes fuses with the egg to form the zygote and the other to the secondary nucleus to form the endosperm. the developing embryo is nourished by the endosperm. A fully developed embryo remains in the ovule and the latter is converted in to the seed. In gymnosperms the female gametophyte nourishes the develoing embryo instead of endosperm and the embryo develops from the zygote inside the archegonium instead of embryo sac.
