An organism's characteristics are controlled by alleles which occur in pairs, each being located on one of the two homologous chromosomes In meiosis the homologous chromosomes segregate and thus the gametes receive only one of a pair of alleles On
fertilisation there is a recombination of alleles, one from the male parent and one from the female Though it is a matter of pure
chance which two gametes combine, every possible combination is actually produced if there are large enough numbers of
offspring

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.
