Write your answer to the following prompt within the space provided. Be sure to answer all parts. Prompt:
In the 1970’s, Benjamin Stacey was born with methemoglobinemia (rr). Neither of Benjamin’s parents were affected by the genetic condition and none of his three siblings showed signs of blue skin, lips, or nails. Since this condition is passed down by genetic traits, his mother was genetically tested and was determined to have a heterozygous genotype (Rr) for methemoglobinemia.

Part A: Determine the genotype for his father and possible genotypes for his three siblings. Provide a brief explanation of your reasoning.
Part B: If Benjamin Stacey were to marry and have children with a woman affected by methemoglobinemia, predict the probability of their children inheriting this condition. Provide a brief explanation of your reasoning.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
