Document Summary
Most common fatal genetic disorder in the u. s. Transports protein that moves chloride ions out of epithelial cells. Maintains a thin film of water on the surface. Obstructs airways and bacteria infects intestines and lungs. Deletion is an allele of the normal cfty gene. Mendel was a monk with training in plant breeding and mathematics. True breeding traits appear the same in all offspring. Discovered that traits of offspring of cross-fertilized pea plants. Each gene has a specific locus on a chromosome. Particular set of alleles that an individual carries is the individual s genotype. An individual with non-identical alleles of a gene is heterozygous. Any mutated gene is a new allele whether or not it affects phenotype. An allele is dominant if its effect masks the effect of a recessive allele. Homologous chromosomes segregate into separate gametes during meiosis. Measure of the chance an event will occur.
