I am no scientist and don't know much about inheritance, but have a few questions. I recently had to do some reading on this and wondered about a few things covered...

A child inherits 23 chromosomes from each parent, giving them 46, right? Therefore, their closest relatives are their siblings. Any offspring they in turn produce will only have half of their chromosomes....

I don't know if science can map what chromosomes children actually do get, but what if this scenario happens:

First child inherits chromosomes 1-23 from both mother and father. Second child receives chromosomes 24-46 from each parent. Are these children actually related?

Actually MJ, the child gets only half of each chromosome from the parents, so there are only 23 total per child, where each half of the chromosome comes from one parent. This is due to the sex cells (sperm and eggs) having a haploid genome, where the cell only has one half of the chromosomes required for cellular viability. As such, the scenario you propose is impossible, as both children would receive half of the chromosomes from each parent, and since both halves from the same person are identical due to replication during cell division, the children would get the same genetic information, except for chromosome 23 which determines the sex of the child.

Hope that helps a bit anyway....

Using the power of licupedia it can be somewhat noted that you have a misconception of 46 individual chromosomes opposed to 23 pairs. Eggs and sperm only get half of each parents 23 pairs.



As noted below there is a great unlikelihood that children will be identical. But with only 4 possibilities per set there most likely be more to have some of the same traits among the children.

With me and my two brothers there are both similar and dissimilar traits. My older brother was more like my mother being short, the same nose and head shape, and poor blind as a bat farsighted although he had my fathers brown eyes. Myself and my younger brother are tall and have my dad's facial traits but my younger brother has mom's blue eyes. He ended up needing glasses when he got older but was nearsighted.
