Three different homozygous strains of corn that produced ears with white kernels were crossed to each other. In each cross, the F1 plants were all red. When F1 plants are crossed, the F2 offspring show a distribution of 9 red: 7 white plants: parents F1 F2 white 1 x white 2 red 9 red: 7 white white 1 x white3 red 9 red: 7 white white2 x white3 red 9 red: 7 white How many genes are involved in determining kernel color in these strains

a metamorphic rock would be formed.

you know that this symptom is misleading and quite often is related to: heart attack

a heart attack is a condition that occurs when the blood flow that transports oxygen to the heart muscle is damaged or cut off completely. the coronary arteries that supply the heart muscle with blood flow can be blocked by the accumulation of plaque. also, when the plaque within the heart artery breaks, it creates blood clot that can also hinder the blood flow. men that are over 45years of age and women that are over 55years of age are at risk of having a heart attack. the symptoms of a heart attack include chest discomfort, chest pain, coughing, and shortness of breath.
