  1. 5. Deoxyribonucleic acid. A molecule that contains the instructions an organism needs to develop, live and reproduce.
  2. 7. An allele or a gene that is expressed in an organism's phenotype, masking the effect of the recessive allele or gene when present.
  3. 9. A diploid organism with two alleles, each of a different type.
  4. 10. Offspring resulting from a true breeding.
  5. 12. The expression of a particular trait, for example, skin color, height, behavior, etc., according to the individual's genetic makeup and environment.
  6. 13. The likelihood of an event to occur.
  7. 17. A diagram that is used to predict the genotypes of a particular cross or breeding experiment.
  8. 18. A form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive.
  9. 19. Responsible for the physical and heritable characteristics or phenotype of an organism.
  10. 21. Simon Says answer
Down
  1. 1. A diploid organism with two alleles, each identical for a single trait.
  2. 2. The study of heredity, or how the characteristics of living things are transmitted from one generation to the next.
  3. 3. Any genetically determined characteristic.
  4. 4. the set of genes in our DNA which is responsible for a particular trait.
  5. 6. A form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.
  6. 8. The result of mixing, through sexual reproduction, two animals or plants of different breeds, varieties, species or genera.
  7. 11. Ribonucleic acid. A nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins.
  8. 14. A set of three adjacent nucleotides, also called triplet.
  9. 15. Adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing.
  10. 16. A gene that can be masked by a dominant gene.
  11. 20. One of the possible forms of a gene.
