Sickle-cell disease is common in tropical and sub-tropical regions because being a carrier, carrying a single sickle-cell mutation (sickle cell trait), affords some resistance to malaria.
1. Law of Segregation: When gametes form, alleles are separated so that each gamete carries only one allele for each gene
2. Law of Independent Assortment: The segregation of alleles for one gene occurs independently to that of any other gene
3. Principle of Dominance: Recessive alleles will be masked by dominant alleles†
No, that would be January.
