This observation is True

Explanation:

Membrane integral proteins can function as ion channels during the transport of molecules through the membrane.

The genetics of a-thalassemia are similar to narrow sense heritability in that there is a gradation of phenotype, with each alle
ki77a [65]

Answer:

In strict mode, the narrow-sense heritability is the proportion of the additive genetic variance that contributes to the total of the phenotypic variance. This value can be associated with the inheritance of the a-thalassemia .

Explanation:

A-thalassemia is a genetic disorder caused by mutations affecting four different genes that encode alpha-globin, thus affecting the hemoglobin production process and, consequently, oxygen transport. The mode of inheritance of the a-thalassemia may be associated with narrow sense heritability since the phenotype is manifested by gradation, i.e., each allele might contribute in similar mode to this genetic condition.
