True/False Slide 73 True Slide 74 In gene therapy a normal allele is placed in a virus, which delivers the allele when it infects its target cell. Slide 75 True Slide 76 An allele inherited on a sex chromosome is called a sex-linked disorder. Slide 77 False, sex- linked gene Slide 78 Environmental influences cannot have an impact on phenotype. Slide 79 False, can Slide 80 Environmental influences can be internal or external. Slide 81 True Slide 82 Gregor Mendel was the first experimenter to trace one trait through several generations. Slide 83 True Slide 84 Mendel called plants that had received different alleles for a trait from each parent genes. Slide 85 False, hybrids Slide 86 A given alleles effect is dominant or recessive.
