Who is genetically closer

But the UNC research shows that inheriting a mutation has different consequences in mammals, depending on whether the genetic variant is inherited from the mother or father. These mice were bred to create nine different types of hybrid offspring in which each strain was used as both father and mother. When the mice reached adulthood, the researchers measured gene expression in four different kinds of tissue, including RNA sequencing in the brain.

They then quantified how much gene expression was derived from the mother and the father for every single gene in the genome. Originally published by Cosmos as Genetically, you are closer to your father.

I promise. Father has two A alleles, mother has two B alleles: all the children will have the genotype AB, which is different to either parent.

Greater similarity to the father is theoretically possible, but very unlikely, because if individual genes favour sibling similarity then it is overwhelmingly likely that the set of thousands of genes will also.

Who is genetically closer, father and son or brothers? Factual Questions. The parents have genotypes AA and BB for a particular gene. All their offspring will have the genotype AB. Nice question, diggleblop! Not all chromosomes cross over. I think. Yes, that sums up how genetics works in Imaginary Land very well. So assuming the alleles A and B are equally distributed in the population. Thanks for the education in this thread.

I can sort of narrow down my own question now. The Human Genome Project suggests fewer than 30, protein-coding genes. And of course the point mentioned above about which of those genes are unique to humans. Half siblings are considered "real siblings" by most because the siblings share some biological relationship through their shared parent. The DNA Relatives feature uses the length and number of identical segments to predict the relationship between people.

Who is genetically closer sibling or child? Asked by: Reyes Prosacco. Can a 1st cousin be a half sibling? What happens if a brother and sister have a kid together? What is it called when a brother is in love with his sister? What is the oldest child syndrome? Are 4th cousins really related? Do you share more DNA with mom or dad? Do sisters have the same DNA? How much DNA does a child inherit from each parent? Which parent determines the height of a child?

Which parent determines skin color? Why is incest a crime? Can siblings marry? What is called when you marry your sibling?

Is it illegal to have a baby with your sister? Is it illegal to sleep with your half sister? Does incest cause birth defects?
