HI
During mitosis, there are two chromatids per chromosome =two chromonemata (according to your book) = two ds DNA(identical), when they separate, one chromatid = one chromosome =one chromonema= one dsDNA.
This should be answer to your first question.

I think they are living as they interact whith living world. And also why biology study them is...they reproduce as reproduce every living thing on the world - transcription, translation of genetic information, replication... that simply belongs under genetics, molecular biology and biochemistry. Or...

Hello friend The first i see now, but still i see that if two genes will recombinate the new sequence of nucleotides must origin thus two new alleles with new phenotype must arise. These new alleles will give new order of aminoacids in proteins which they are coding. This i think cannot work cause i...

If im thinking about mendelian genetics for example we have given one recessive allele and one dominant all...
