TermDefinition
Genetics study of the herédity patterns and variation of organism.
Heredity the biological process whereby genetic factors are transmitted from one generation to the next
Alleles any of the alternative forms of a gene that occurs at a specific place on a chromosomes.
Trait characteristic that inherited.
Dominant allele that is expressed when two different alleles are present in an organism’s genotype.
Recessive allele that is not expressed unless two copies are present in an organism’s genotype.
Genotype collection of all an organism’s genetic information that codes for traits.
Phenotype collection of all of an organism’s physical characteristics.
Homozygous characteristics of having two of the same alleles at the same locus of sister chromatids.
Heterozygous characteristics of having two different alleles that appears at the same locus of sister chromatids.
Punnett square model for predicting all possible genotypes resulting from a cross or mating.
Mutation change in the DNA sequence.
Autosome(s) chromosomes that contains genes for characteristics not directly related to the sex of the organism.
Sex chromosome chromosomes that directly controls the development of sexual characteristics.
Sex-linked gene that is located on a sex chromosome.
Deoxyribonucleic Acid (DNA) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information.
Ribonucleic Acid (RNA) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes; it transmits genetic information from DNA to the cytoplasm and controls certain chemical processes in the cell.
Replication process by which DNA is copied.
Nitrogenous bases confused or stuporous state caused by high levels of dissolved nitrogen in the blood.
