Answer:
Explanation:
LHON (Leber Hereditary Optic Neuropathy): Is a disease that is characterized by loss of vision in young adults.
Sickle cell anemia: Is a disease characterized by production of abnormally shaped red blood cells, that is, not round in shape as normal but are 'sickle' shaped or elongated/crescent shaped.
Both diseases are heritable But LHON is caused by mutations existing in the mitochondrion thus only inherited maternally.
Sickle cell anemia is caused by mutations in the HBB gene which produces the beta subunit of hemoglobin. It is inherited from recessive genes of both parents.
Genetic engineering is a big part of agriculture. that would be your answer
When a trait is recessive, an individual must have two copies of a recessive allele to express the trait. Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an a genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
