Suppose a dominant allele (N) codes for a big nose and a recessive allele (n) codes for a small nose. Imagine that an organism receives a dominant allele from its mom and a dominant allele from its dad. What can be determined about its genotype and phenotype? A. The organism has a small nose, because it's homozygous. B. The organism has a small nose, because it's heterozygous. C. The organism has a large nose, because it's homozygous. D. The organism has a large nose, because it's heterozygous.
