  1. Having different alleles for any one gene
    Heterozygous
  2. Having identical alleles for any one gene
    Homozygous
  3. Any of two or more variants of a gene that have the samerelative position on homologous chromosomes and are responsible for alternative characteristics, such as smooth or wrinkled seeds in peas
    Allele
  4. The ability or tendency of an organism or cell to maintain the internal equilibrium by adjusting its physiological processess
    Homeostasis
  5. The passing of traits to offspring
    Heredity
  6. A heterozygous condition in which both alleles at a gene locus are partially expressed, often producing an intermediate phenotype
    Incomplete dominance
  7. The physical appearance of an organism as distinguished from its genetic makeup: depends on which genes are dominant and on the interaction between genes and enviroment
    Phenotype
  8. The genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms
    Genotype
  9. The characteristic chromosome complement of a eukaryote species. The preparation and study is part of cytogenetics
    Karyotype
  10. Relating to the form of gene that is not expressed as a trait in an individual unless two suc genes are inherited, one from each parent
    Recessive gene
  11. An allele that produces the same phenotype whether its paired allele is identical or different
    Dominant gene
  12. The sequence of nucleotides in DNA or RNA that determines the specific amino acid sequence in the synthesis of proteins. It is the biochemical basis of heredity and nearly universal in all organisms
    Genetic code
  13. A pyrimidine base that is a component of DNA. It forms a base pair with adenine
    Thymine
  14. A pyrimidine base that is a component of RNA. It forms a base pair with adenine during transcription
    Uracil
  15. Any compounds consisting of a necleoside combined with a phospate group and forming the basic constituent of DNA and RNA
    Nucleotide
