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).
The surgical procedure that uses a blood vessel from another part of the body to channel blood around an occluded coronary artery is the coronary Artery Bypass Graft. This is a procedure that restores blood flow to the heart muscle by diverting the flow of blood around a section of a blocked artery in the heart. Specialists use this procedure to treat people who have severe coronary heart disease, a disease in which a waxy substance called plaque builds up inside the coronary arteries.

<span>As humans cause more carbon dioxide to be released into the Earth's atmosphere, it causes the oceans to become much more acidified which in turn begins to damage the precious coral reefs. Roughly one quarter of all the life in the ocean is dependent on coral reefs for food and shelter.</span>
