How does increasing the density of a gas affect it's pressure?

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
