How can mendel's principles be used to study human traits?

 apply to peas as they apply to human chromosomes. 
His first law was the law of segregation and it states that the two alleles of and individual are segregated (separate) and passed on to the next generation singly. 
this is exactly what happens to chromosomes at the end of meiosis 2.Gametes 

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
