The only way to get a child from three parents is the method of cytoplasmic replacement within the framework of in vitro fertilization technology. Only two women and one man will participate. The method is practiced to avoid certain mitochondrial diseases in a child, including diabetes mellitus accompanied by deafness. The essence of the procedure: the nucleus of the egg of the recipient woman is transplanted into the cytoplasm of the egg of the donor woman. Then the hybrid egg is fertilized with sperm. The purpose of the procedure is to replace the cytoplasm with defective mitochondria of the recipient with the cytoplasm of the donor with healthy organelles. Mitochondrial diseases are transmitted only through the female line to children of both sexes, since the sperm transmits half of the nuclear genome to the zygote (most of the mitochondria of the sperm are in the flagellum), and the ovum supplies both half of the genome and mitochondria. Unlike chromosomal diseases, the development of a treatment for which is shouldered by genetic engineering, mitochondrial ones have a panacea to be a relic of the past, because mitochondrial DNA encodes about 37 genes, which cannot compete with 28 thousand active genes of all human hereditary material.

Of course it can. And if a girl masturbated with a water jet, then the child will be water, if the sex was in a condom, then rubber. It’s scary to imagine WHO would be born if the poor thing had a chance to use tampons!

no, not really.

in addition to the previous answer.

Update your knowledge about the processes of cell division, especially about the division of germ cells, about fertilization (textbooks write well about this on gynecology for universities, for example, Savelyev) and the very foundations of school genetics about the diploidy of somatic cells and the haploidy of germ cells.

if very very rough and simplified: a woman and a man have germ cells (egg and sperm) and they contain a half set of chromosomes (23 of 46, as a result of meiosis), when fertilized in a zygote (merged sperm and egg, which have now become one large cell) in total there will already be 46 chromosomes, but there is only one cell, from which an organism with many cells that form tissues, organs and systems should be formed. But this cell will divide already by mitosis, that is, from one, two completely identical ones with 46 chromosomes will be rejected (remember mitosis, DNA replication and replication characteristics). first there will be 2, then 4, 8, and so on and so on .....

And in each such cell there will be 46 chromosomes, half from the mother's egg, half from the father's sperm.

And all cases when in the course of violations in the cells there are more or less chromosomes lead to pathology: early abortion, stillbirth, severe anomalies and malformations (the most famous example of Down syndrome, when chromosomes in the cells of the body 47)

When you remember and update in your head the knowledge about these processes, you yourself will be surprised at this question.

This theory is called "telegony", and Aristotle believed in it. ru.wikipedia.org Many centuries ago, many biologists believed (more or less) that genetic information, having entered the female body with the sperm of a partner, could somehow be delayed for a very long time. For example, it was assumed that a woman could become pregnant from one man; some time from another; and the second fetus may contain some genes from the previous one. Or it was assumed that even if fertilization did not occur, all the same, the genetic material could somehow remain and take part in the next fertilization. Similar effects were actually found in fruit flies (source, in English onlinelibrary.wiley.com) But no one has surrounded anything similar in humans or other mammals.

It is not genetic material that is more dangerous, but pathogens and all kinds of chemistry.

The concept of telegony is that all the former sexual partners of a woman, regardless of whether she gave birth to them or not, pass on a number of their key features (appearance, physique, and others) to her children from subsequent men. Moreover, the first sexual partner has the greatest influence in this sense. This concept has a long history - even Aristotle wrote about it. At first, official biology considered telegony quite seriously, but subsequent genetic studies and numerous experiments demonstrated its inconsistency.

Answer 9
May, 2021

Let's just say: it is not proven.

Moreover, geneticists are convinced that heredity is determined EXCLUSIVELY by the genotype, i.e. DNA chains in chromosomes. And in many respects this is true: at least, the genotype, in a first approximation, is constant throughout life, therefore the same chromosomes enter the germ cells. Moreover, it is believed that ALL eggs are formed in advance and only mature by the time of ovulation (although each cell has its own finite lifespan, and how it can exist for years and decades is a mystery).

However, any living cell inevitably participates in the metabolism - she needs food, oxygen, and so on. Therefore, it is inevitably influenced by the body. And how it affects, including on gametes, is not fully understood.

Answer 10
May, 2021

If we mean whether the first sexual partner affects children from other partners - then no, this is an anti-scientific myth known as telegonia.

Modern science knows for sure that:

1) A child inherits the genes of only his parents, that is, two people from whom he was conceived.

2) By itself, sexual intercourse - neither the first, nor the second, nor any - does not change the genes of the sexual partner.

Thus, a child can have at least some genetic relationship to the first sexual partner in the only case - if he is conceived from him.

If the child is conceived from another partner, then the first the sexual partner has nothing to do with the appearance and other characteristics of the child.

Answer 11
May, 2021

The genome of a child is determined at the time of conception strictly as a result of the fusion of ONE sperm and ONE egg. If two eggs are fertilized simultaneously by two different sperm (cases of fertilization of several eggs of one partner by different partners in a short period of time are described), two children will be born with a set of genes from different partners, but mutual influence cannot occur.

The fertilization of an egg by several sperm cells simultaneously is also described and is a rare disorder (polyspermia), as a result of which a non-viable zygote is obtained.

Thus, the child's genome is influenced only by his parents, who, in fact, formed this genome from their .

No conception - no child, therefore, partners, intercourse with whom did not lead to conception, cannot influence the child's genome in any way.

Answer 12
May, 2021

If a woman sleeps with different men, this does not affect the genome of her children. Apparently, the author of the question had in mind telegony - the belief that all the children of a woman will look like her first man. Dog breeders are especially susceptible to this belief, who carefully monitor that the first dog was as thoroughbred as possible.

Answer 13
May, 2021

No, not true! Multiple sexual relations lead to a high risk of infection with sexually transmitted diseases, which can adversely affect the ability to conceive and bear a healthy child.

The genome of the unborn child is influenced by factors leading to mutations in the germ cells of the expectant mother and the future father, as well as their influence on the already fertilized cell.
