in 2N eukaryote species, most genes within the nucleus obey Mandel's patterns. Homologous pairs of chromosomes segregate during meiosis. Sex linked traits offspring's inherit one copy of each gene from each parent. Nuclear Genes - sorting of chromosomes during meiosis - genes on the chromosomes in the nucleus. Chloroplasts and Mitochondria are not sorted during meiosis and do not segregate into gametes.
