en CR ANN PAOLA 33 alleles: alternate forms or varieties of a gene. chromosomes: thread-like, gene-carrying bodies in the nucleus of a cell. dominant allele: an allele that masks the presence of a recessive allele in the phenotype. Double heterozygote: An individual who is heterozygous for two mutations at two separate genetic loci that together are sufficient to manifest a phenotype. Differs from compound heterozygote. Somatic: Refers to tissues that are not within the germline. Somatic mutations arise in the somatic tissues and are therefore not passed from parent to offspring. Somatic mutations are common in neoplasms. Marker : A locus with alternative alleles that can be used in genetic mapping experiments. DNA: is composed of sugars, phosphates and bases arranged in a double helix shaped molecular structure. Genes: units of inheritance usually occurring at specific locations, or loci, on a chromosome. heterozygous : a genotype consisting of two different alleles of a gene for a particular trait (Aa). hybrid: offspring that are the result of mating between two genetically different kinds of parents--the opposite of purebred. HUGO : Human Genome Organization. Erythrocytes : the hemoglobin-containing cell found in the blood of vertebrates. Euchromatin : the chromatin that shows the staining behavior characteristic of the majority of the chromosomal complement. Autosome: a nuclear chromosome other than the X- and Y-chromosomes. Ploidy :The number of sets of chromosomes present in an organism or cell. Recombinant :Refers to offspring whose genotype and phenotype combinations differ from their parents, implying genetic recombination between the loci under study. Telomerase : Enzyme that extends the length of telomeres. Methylation :The addition of methyl groups to cytosine in DNA. Heteroplasmy : The occurrence in a single cell of more than one different population of mitochondrial DNA sequence Phenotype: the observable or detectable characteristics of an individual organism--the detectable expression of a genotype. Probability: is usually expressed as the ratio of the number of actual occurrences to the number of possible occurrences. Sex Cell : a gamete, either a sperm or an ovum. sperm : a male sex cell or gamete. zygote : a "fertilized" ovum. Mitosis : nuclear division. Trait : any detectable phenotypic property of an organism. Transcription : the formation of an RNA molecule upon a DNA template by complementary base pairing. punnet square: a diagram used to organize all the possible combinations of offspring from particular parents Centromere : a region of a chromosome to which spindle traction fibers attach during mitosis and meiosis Gregor Mendel : Father of Genetics Chromosomes: in the eukaryotic nucleus, one of the threadlike structures consisting of chromatin and carry genetic information arranged in a linear sequence. Gamete: Mature germ cell, egg or sperm Mature germ cell, egg or sperm Fertilization :Union of the egg and sperm geneticists: scientists that study heredity are called ________. amino acids: Proteins are made of smaller units called _________.
