Since genes on various chromosomes are not physically connected to one another, they assort separately during meiosis. The inheritance of a gene on one chromosome does not alter the inheritance of a gene on a separate chromosome, according to this statement. Unless the genes are placed on the same chromosome, Gregor Mendel's law of independent assortment holds that alleles of various genes assort independently of one another during gamete production. As a result, during meiosis, genes on various chromosomes are free to recombine and assort independently, leading to novel allele combinations in the progeny.

Option 1 is the correct answer.
