Question

Meiosis is the process of diploid germ cell division to produce haploid gametes in sexually reproducing organisms. What aspect of chromosome behavior most clearly accounts for Mendel's law of segregation? What aspect of chromosome behavior most clearly accounts for Mendel's law of independent assortment? What other process greatly contributes to genetic diversity during meiosis, and at what stage of meiosis does this process occur? 

Answer 1

Movement of homologous chromosomes to opposite poles at anaphase I of meiosis mostly aspect of chromosome behavior most clearly accounts for Mendel's law of segregation

Independent alignment of different homologous pairs on the metaphase I spindle mostly aspects of chromosme behaviour most clealry accounts for mendels law of independent assortment  

Mendels principle of segregation also states that alleles seperate from each other before forming gametes ...at the end of the meiosis 2 each of the daughter cells contains one full set of chromosomes each with a single chromatid ..Mendels also said that the traits which had disappeared in F1 generation reappeared in F2 generation beacause traits can be expressed by dominant alleles or recessive alleles and the recessive traits are obscured by dominant one in F1
