Answer:
Methemoglobinemia
Explanation:
Methemoglobinemia (also known as the blue baby syndrome), is a condition with multiple etiologies which is associated with the lack of oxygen in the blood. This syndrome affects the function of red blood cells by altering the amount of hemoglobin protein, which carries and distributes oxygen to the body. Methemoglobinemia may be acquired by exposure to drugs and/or toxins. In this regard, it has been shown that high levels of nitrates in the water may induce this syndrome in infants.
Heritability is a measure that is used to estimate the variation of phenotypic traits (observable traits) in a given population due to the variation or changes in the genetic make up (genotype) among certain individuals. some of these traits includes color blindness, tongue rolling and curly hair among others. However, some traits such as nearsightedness are caused or influenced by the changes in the environment and therefore Heritability is not a factor to consider when dealing with such traits.

The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is
