Hi!
I have a question where they ask me to say that what the genetic recombination, chromosome segregation are, and the biological importance of each of these concepts.
I know that genetic recombination is a process that occurs in the first meiotic division, specify in prophase I (subphase: pachytene), and consists of the intersection of two of the four chromatids of homologous chromosomes to form a bivalent, beginning the interbreeding with rupture of the two double DNA chains and subsequent alternative splicing, joining in a single fiber of the genes of a chromatid.
And the biological importance of genetic recombination, as a source of variable characters, would be the contribution to the phenomenon of evolution of species, right?
However, I do not know what is chromosome segregation, nor what is its biological significance.
Could you help me, please?
Thanks!

come on, that’s not on Google?

that’s the process, when chromosomes pairs and are divided into two new cells, from each pair just and exactly one 😉I hope the importance is clear from that.
