You possess two alleles for each of your genes. (One from the paternal side and one from the maternal side in each homologous pair of chromosomes.) In simple inheritance, having at least one dominant allele (form of the gene) means you will display the dominant phenotype, and the only way to display the recessive phenotype is to have two recessive alleles. For example, individuals with the genotypes RR and Rr can roll their tongue (into a U shape). If you cannot roll your tongue, then you know with certaintly you have the genotype rr. If you can roll your, you would write your genotype as R- (R followed by a dash since you might not know if you are RR or Rr, but either way, you display the dominant phenotype because the first letter is capital.)

You possess two alleles for each of your genes. (One from the paternal side and one from the maternal side in each homologous pair of chromosomes.) In simple inheritance,
having at least one dominant allele (form of the gene) means you will display the dominant phenotype, and the only way to display the recessive phenotype is to have two
recessive alleles. For example, individuals with the genotypes RR and Rr can roll their tongue (into a U shape). If you cannot roll your tongue, then you know with certaintly you
have the genotype rr. If you can roll your, you would write your genotype as R- (R followed by a dash since you might not know if you are RR or Rr, but either way, you display the
dominant phenotype because the first letter is capital.)
