Genetics recap: Match Terms and their definitions. 25: One of two or more versions of a gene. Example: Z: Allele: 25 1: A particular Variant of a phenotypic characteristic. A: Genetic Variation:______ 2: Variation in DNA sequences. Results in different forms of genes. B: Chromosomes: _______ 3: Found in the nucleus of the cell, these structures are made up of tightly coiled DNA. C: Meiosis:________ D: Mitosis:__________ E: Genotype:________ F: Phenotype:_______ G: Mutation:_________ 4: type of cell division in sexuallyreproducing organisms used to produce the gametes, such as sperm or egg cells. Results in four cells with only one copy of each chromosome. 5: Type of cell division that results in two identical cells, the number of chromosomes are maintained. 6: The genetic makeup of an individual. H: Heterozygous:_________ I: DNA:_________ 7: The appearance of the organism (physical expression of the genotype.) 8: A change in the DNA sequence. J: Traits:________ 9: Each chromosome contains a different allele for the gene (one dominant and one recessive.) 10: A self-replicating material which is present in nearly all living organisms. It is the carrier of genetic information.
