Hooked nose is dominant to pointed nose.

- Nn:
- nn:

Answer :

Final answer:

In genetics, 'NN', 'Nn', and 'nn' are genotypes representing dominance and recessiveness, in the given context for the shape of a nose. 'NN' is a homozygous dominant genotype (hooked nose), 'Nn' is a heterozygous genotype (also hooked nose), and 'nn' is a homozygous recessive genotype (pointed nose).

Explanation:

In the context of dominant and recessive genes, the given question is about a specific trait - the shape of the nose. The letters NN, Nn, and nn represent different genotypes, or genetic combinations, for a trait.

The notation NN refers to a homozygous dominant individual, where both alleles for the nose shape are dominant, resulting in a hooked nose. Nn represents a heterozygous individual, where one allele is dominant (hooked nose) and one allele is recessive (pointed nose), but because the dominant trait overpowers the recessive, this too results in a hooked nose.

The genotype nn is homozygous recessive, meaning both alleles are recessive, leading to the expression of the recessive trait, a pointed nose.
