Do human genes from past generations of family continue to revolve?

Question

Like genes from my grandparents from 4 generations ago.
that is equivalent to like 150 years ago or more. Do they come up into other family members that are born later?

Answer 1

Genetic material (DNA) in genes from both your parents can swap liked shuffling a deck of cards. In such cases, the original genes are replaced with new modified ones that are a patchwork mix of the parental genes. On the other hand, depending upon the gene regions and degree of shuffling, many stretches of DNA (most in fact) can be passed on over generations without mixing from the two parents and show up as traits in descendents over many generations.

Answer 2

Based on what I konw, the answer is no.
When you talk about evolution, you are talking the length of time. Giving 150 years is nothing compare to 100000 years or even more to run the process of evolution.
It is true that the previous generation can have chances to pass altered DNA material to next generation. such as exposing the germline to radioactive material or chemical material.
Then you will see the process of evolution occure but it will not be selected as the best generation for surviving the environment.

If you look at single-cell organism or viruses, the mutation can occure very frequently. For those micro-organism like virus, they just need few days to have 1000 times of new generations. Can you imagine the rate of mutation compare to human.
For example, 10 cycles of generation will take total 400 years for human race. the virus take 3 days to have 1000 cycle of generation. I called it the crazy of evolution.

Answer 3

yes, chromosomes are passed on and on over generations - you have 23 pairs of chromosomes in most of your cells. yes, they are numbered 1-23. one chromosome of of each pair comes from your mom, the other from your dad. in your sperms or eggs, whatever your gender is, there will be only 23 chromosomes, not pairs, logically, so your child may get some chromosomes of your father, some of your mother but never the same chromosome from both, because your sperm or egg has only one chromosome no1, one chromosome no2, etc. the selection of what chromosome from each pair will go to what sperm is random. As was said here, it is like shuffling cards. so chances are you have chromosomes from many many ancestors of yours.
yes, you can trace a gene back across generations, sadly, they are usually gene-based medical conditions where you can see it, because thats what showed up.

but if you wanted to say evolve instead of revolve, i would say that 150 years is not much for some change in the meaning of the genes - only some insignificant mutations - like typos of the genetic code, occur over time or maybe some significant mutation tha may cause severe troubles - even one "typo" can be fatal, if it is in important part of the gene. The actual evolution omes with necessity to survive in the world, and humans have medical care that allows even very sick people to survive (like thats good of course) but also to REPRODUCE and pass their syndromes on so we are just accumulating defficiencies instead of evolution. Sad but true.

Answer 4

I do not know if they revolve----or evolve for that matter but they do, however, show up from time to time if you are talking about genes that are recessive and will produce problems in the offspring.
