1.The father is able to roll the tongue because the allele for the ability to roll the tongue is dominant over the allele for the inability to roll the tongue
2.(BO) Father's Genotype
3.A maternal effect is a situation where the phenotype of an organism is determined not only by the environment it experiences and its genotype, but also by the environment and genotype of its mother.
4.The mother's genotype is AO
5.Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism
(the physical trait associated with that genotype)
