Why do zygotes get half their DNA from their mom and half from their dad?

Zygotes get half of there DNA from both the father and mother because during fertilization, only a haploid number of chromosomes is released for fussion, i.e 23. When both parents releases 23 each, it makes up 46.

∙ 12y agoIn every human being there are 46 chromosomes (organized structure of DNA and protein found in cells). When fertilization occurs, the newly formed child will get half of it's chromosomes from it's mother, and the other half from it's father. If the gametes (sperm and eggs) were not haploid (each chromosome has two sets, a haploid is only one set of each chromosome) then the child would have 92 chromosomes. If that did happen then the child would end up having certain diseases one example would be Down syndrome.

∙ 13y agoso that the child will get aspects of both there parents because if it was just one gene then it would just be a replicare of whos ever gene was used up
Wiki User
∙ 9y agoYour genetic material is included in your chromosomes. Since you get half of your chromosomes from each parent, you get half of your genetic material from each parent.

∙ 14y agoDuring contraception obviously :| so like the two sets of alleles from each parent kinda join, and this blatantly happens so that a baby can be made :|
Wiki User
∙ 12y agoso that a normally contented cell is produced after the fusion of the two half DNAs
Wiki User
∙ 12y agoBecause 23 chromosomes come from your mom and the other from your dad so when the baby is forming it has 46 chromosome.

What are 3 practical applications of DNA fingerprints?
your mom your dad and you
Human cells have how many chromosomes?
46 chromosomes (23 pairs) half from the mom half from the dad
If there are 46 chromosomes in a human body where does half come from?
Half come from your mom's egg and half come from your dad's sperm.
What kind of offspring are produced from sexual reproduction?
Offspring that are genetically different from its parents. Each parents contributes half the number of chromosomes, therefore the offspring has genes from its mom and from its dad.
Do the offspring look exactly like their parents reproduction?
No. The offspring receive a combination of both parents DNA (roughly half from each parent although the mom contributes more due to mitochondrial DNA). During recombination the DNA of both parents is combined form a unique individual with traits from both the mother and father.
Do you share half your DNA with your mum and half with your dad?
we get half of our DNA from mom and half from dad. This really tells us how related we are to each of our parents.
Who do you get your DNA from?
Its a combination of your mom's and you dad's. Identical twins have the same dna
Why do you inherit a fourth of your grandparents' DNA?
Because your mom or your dad inherits half of their DNA from your grandparents. And since you receive half of the half of DNA that your grandparents had, you get fourth of your grandparents' DNA.
How much DNA is passed down to your children?
I think it's 50 50 as in half mom and half dad.
Are Justin biebers half siblings from mom or dad?
his half siblings are from his dad
What percentage of the DNA is passed through to the offspring in asexual reproduction?
An offspring receives half of its genetic information from its mother, and half from its father.
Are justin biebers half siblings from his dad or mom?
Dad.
What are 3 practical applications of DNA fingerprints?
your mom your dad and you
What do you call a sister who has a different mother?
If you have a sister with the same dad but different mom, then she's probably your half-sister, although she would have about 25% of the same DNA as yours.
Can the DNA of a baby be determined by swabbing the mother's mouth while she is pregnant?
No, that will give you the genetic markers of the mom, not the baby. Mom contributes half the DNA of the child, Dad contributes the other half. You can't really determine what genes the baby will get by just looking at the parents, but you might could tell what genes the child has a chance of receiving.
What is Lana Parrilla's ancestry?
Lana Parrilla is a/an Actress
Does a baby get half of its DNA from mom?
you see, every human has 46 chromosomes, which are genetic material. during sex, 23 chromosomes are in the sperm cell, and 23 in the egg cell, so when the baby is formed, it has half of its moms, and half of its dads genetic material.
