9 49. The most significant adaptive advantage of sexual reproduction is that it a. may be a lot of fun b. allows to combine genes of two or more individual organisms c. reduces by half the parental numbers of chromosomes in offsprings d. may prevent the expression of recessive alleles of one of the parents in the offspring e. introduces variation into genetic make up of offspring 50. Modern studies of many disorders (like Marfan syndrome) have demonstrated that silent mutations a. result in the production of the same protein due to the redundancy of the genetic code and therefore never have effect on phenotype b. may sometimes result in the production of abnormal amount of the same protein due to changes in the speed of transcription and alternative RNA splicing c. may sometimes result in the production of abnormal amount of the same protein due to changes in the translation control mechanisms d. b and c above e. are not possible to observe in humans
