Why are lethal dominant alleles so much more rare than lethal recessive alleles?

a. the lethality associated with lethal dominant alleles is much more severe than that associated with lethal recessive alleles.
b. the types of mutations that create lethal dominant alleles are much less frequent than those that create lethal recessive alleles.
c. less is known about lethal dominant disorders, so the rareness of these alleles is an artifact due to a lack of detection.
d. lethal dominant alleles are harmful whether they are carried in homozygous or heterozygous form, so there is always strong selection against these alleles.

Some technological solutions to problems like global warming meet the specific needs and situations of local communities. an example from india involves converting the solid waste from cattle into clean-burning fuel for cooking. this reduces the amount of greenhouse gases, specifically methane and carbon dioxide, released into the environment from wood fires. when evaluating the feasibility of implementing this solution, computer models are used to weigh costs against benefits. what factor is least likely to impact the decision on adopting this technology?
