Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).
I hope you get the answer!!!
I believe CODIS still exist because if there is anything new about DNA in a laboratory, it will go straight to CODIS>
Answer:The reaction yields something I think...♀️
Explanation:
Prokaryotic are the cells that dont have a necleus or other important membranes of a cell and eukaryotic are just normal cells i think
Answer: linear or circular. include genes encoding viral proteins: capsid, envelope proteins, any polymerase not found in the host cell. viruses may have a lipid envelope.
