The allele h codes for ldl receptors that are needed to metabolize ldl. people who are hh have healthy levels of ldl, whereas those who are hh have dangerous levels of cholesterol that often lead to heart attacks and death during childhood. interestingly, those who are hh have high levels of cholesterol and are at risk of a heart attack as a young adult, but if their cholesterol is managed, they will have a long life. this is an example of

incomplete dominance.

Explanation:

According to my research on studies conducted by various geneticists, I can say that based on the information provided within the question this is an example of incomplete dominance. This refers to partial inheritance of one allele for a certain trait which causes the formation of a third phenotype that triggers a physical trait that results in the combination of both alleles phenotype's.

I hope this answered your question. If you have any more questions feel free to ask away at .

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
