Are human chromosomes carrying identical genetic information?

Question

If not then during cell multiplication how do identical chromosomes (carrying same genetic information) from different parents come close together for exchange of genetic information?

Answer 1

No, you get a unique chromosome from each of your parents. What's important during chormosome pairing in mitosis and meiosis is that matching chromosomes share the same organization, meaning that the centromeres are in the same location, the arms are the same length, etc....

Answer 2

During meiosis there is a stage in which genetic information "crosses over", meiosis is a two mitosis stage division of gametes. As these gametes (haploid cells) come together during sexual reproduction, their chromosomes combine to give the diploid cell called a zygote, which then develops into the new organism.

It is during the stage when both cells come together that the genetic info is shared between parents.

Answer 3

i'm now no longer likely to go loopy in this respond, notwithstanding I took a direction on developmental psychology my freshman year. relatively, a character's sexuality is observed with tips from skill of three concerns: their genes, and their environment, and their determination. of course, anybody could additionally be born gay because of the undeniable fact that for the period of their genetics. additionally, anybody could be born unclear, and by using the undeniable fact that for the period of their environment are moved in one direction or the alternative. And, for some human beings, it is by using the undeniable fact that they only opt to. the reasons some units of twins are/are not each and each gay is by using the undeniable fact that of the latter 2 components. purely because of the undeniable fact that they are twins does now no longer constantly advise that they are going to do precisely the comparable concerns constantly. This unshared environment could precipitate particular differences in one twin, relative to the alternative. that's why there is an approximate 50% danger. that 50 comes from genes, in spite of the twins have in hassle-free it is not significant what they do. the different fifty share comes from the ambience. (determination isn't factored into the p.c., for the reason that that's in spite of interior take care of of the character--the alternative 2 are not--in spite of the indisputable fact that this could additionally come into play)
