blood are low, for example during vigorous exercise. Lactic Acid A breakdown of anaerobic respiration in muscle cells. Oxygen Debt The oxygen that the body needs after vigorous exercise. Biology Unit 2.5 Simple inheritance in plants and animals. – Key Word Definition Allele One form of a gene. Different alleles of the same gene produce slightly different characteristics, such as different eye colours. Carriers A person carrying one allele for a recessive disorder, so they do not have the disorder themselves but could pass it on to their children. Cystic Fibrosis An inherited disorder caused by a recessive allele that result in the production of thick, sticky mucus, affecting the lungs and other parts of the body. DNA Fingerprints (profiling) A process that produces an image of variable sections of DNA, used to identify individuals. Dominant In genetics, an allele is dominant if it produces its form of the characteristic in the organism even if only one chromosome of the pair carries the allele (that is, whether the organism is homozygous or heterozygous). Genetic Disorder A disease/disorder that can be inherited due to a mutation of DNA
