Purpose: To determine whether intragenic changes modulate the cystic fibrosis (CF) phenotype in individuals who are positive for the I148T allele. Methods: The genes from individuals who carried at least one copy of the I148T allele were analyzed for additional changes that may be acting as genetic...Recessive allele q = 0.1 Dominant allele p = 0.9 Recessive phenotype q2 = 0.01 Homozygous dominant p2 = 0.81 Heterozygous 2pq = 0.18 1% of the population will be gray 99% of the population will be black A population of 134 lizards has 81 individuals with green skin and a gg genotype.
Watch a video to explain what cystic fibrosis is, how it is inherited and to illustrate the severity of the disorder (see resources). Evaluate genetic modification to treat cystic fibrosis. Produce notes and complete genetic diagrams to explain how polydactyly and cystic fibrosis are inherited.
