NOTES > Genetic Diversity and Chromosome Variation

Segregation, independent assortment of chromosomes, and fertilization result in genetic variation in populations. The chromosomal basis of inheritance provides an understanding of the pattern of transmission of genes from parent to offspring. Certain human genetic disorders can be attributed to the inheritance of a single affected or mutated allele or specific chromosomal changes, such as nondisjunction. Some traits result from non-nuclear inheritance

a. Chloroplasts and mitochondria are randomly assorted to gametes and daughter cells; thus, traits determined by chloroplast and mitochondrial DNA do not follow simple Mendelian rules.

b. In animals, mitochondria are transmitted by the egg and not by sperm; as such, traits determined by the mitochondrial DNA are maternally inherited.

c. In plants, mitochondria and chloroplasts are transmitted in the ovule and not in the pollen; as such, mitochondria-determined and chloroplast-determined traits are maternally inherited.
