Explanation:

The results are explained if the trait blue eyes is dominant (B) over non-blue (b) and the dominant allele B is lethal in homozygous individuals.

<u>The possible genotypes and phenotypes are:</u>

  • Homozygous dominant (BB): lethal
  • Heterozygous (Bb): blue eyes
  • Homozygous recessive (bb): non-blue eyes

When blue (Bb) is crossed with non-blue (bb) the resulting offspring is 1/2 blue (Bb) and 1/2 non-blue (bb).

When non-blues interbreed (bb X bb) all progeny is non-blue (bb).
