Umar is honored for his attempt to resolve the fiscal problems attendant upon conversion to Islam. During the Umayyad period, the majority of people living within the caliphate were not Muslim, but Christian, Jewish, Zoroastrian, or members of other small groups. These religious communities were not forced to convert to Islam, but were subject to a tax (jizyah) which was not imposed upon Muslims. This situation may actually have made widespread conversion to Islam undesirable from the point of view of state revenue, and there are reports that provincial governors actively discouraged such conversions. It is not clear how Umar attempted to resolve this situation, but the sources portray him as having insisted on like treatment of Arab and non-Arab (mawali) Muslims, and on the removal of obstacles to the conversion of non-Arabs to Islam.
What was another term for Muslims who were not Arab?
A: mawali

Genes can acquire mutations in their sequence, leading to different variants, known as alleles, in the population. These alleles encode slightly different versions of a protein, which cause different phenotype traits. Colloquial usage of the term "having a gene" (e.g., "good genes," "hair colour gene") typically refers to having a different allele of the gene. Genes evolve due to natural selection or survival of the fittest of the alleles.
What do alleles do?
A:
encode slightly different versions of a protein
