5. a summer-squash plant that is true-breeding for disc-shaped fruit is crossed with a summer-squash plant that is true-breeding for long fruit. all the f1 progeny have disc-shaped fruit. when the f1 progeny are intercrossed, f2 progeny are produced in the following ratio: 9/16 disc-shaped fruit: 6/16 spherical fruit: 1/16 long fruit. a.(1 pt) use generic gene symbols a and b for the two loci and give the genotype for each parent, the f1 progeny, and each f2 progeny. b.(1 pt) what phenotypic and genotypic ratios would be expected in a backcross between the f1 progeny and the parent with long fruit?

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.
